  • Product Description

    A stylish, discrete, and wearable necklace version of the Grabber|||Made in the USA, ARK's Krypto-Bite™ Chewable Gem Necklace provides a safe, wearable, and discreet solution for kids and adults who need to chew. For boys, it's cool-factor Krypto-Bite™. For girls, it's a stylish gem pendant. Either way, it's sure to be a hit!  Use this "chewelry" as an oral fidget (or even hand fidget) to help calm, soothe, and self-regulate during times of stress, or to better focus during homework and other activities. Modeled after the extension of the Grabber®, the prism-shaped pendant also comes in 3 color-coded toughness levels:

    • soft (magenta or red) - recommended for mild chewers
    • XT (lime green or teal or black) - XT stands for "Xtra Tough," recommended for moderate chewers
    • XXT (blue or purple) - XXT stands for "Xtra Xtra Tough," recommended for more avid chewers

    Choose your option from the menu above. Each pendant is sold individually with its own breakaway necklace cord. Or, you can also buy more than one pendant and create your own custom statement chew necklace (like the first picture, for example). Color hues may vary slightly.

    Made in the USA  Designed, manufactured, and assembled in the USA by ARK Therapeutic.  Medical grade, FDA compliant, NO lead, phthalates, PVC, BPA, or latex.

    Caution Caution: This product is not a toy.  The clasp and cord are not intended for chewing.  Contains small parts that may pose a choking hazard - direct supervision required.  Recommended for ages 5 years and up.  Although these chew tools are sturdy and durable, no chew tool is indestructible.  Wear/tear may be expected given the nature of the intended use.  How long they last is typically equal to the amount and intensity of the chewing, as well as other variables (such as jaw strength, stress/anxiety levels, if other sensory strategies are in place, etc.).  While for some people a chew tool will last forever, for others with heavy/aggressive oral needs, they may go through it very quickly.  Please supervise at all times and replace if necessary if the item shows signs of wear and tear.  For the longest lasting chew tool overall, click here. 


    • 15 years ago, ARK's Grabber® was the first solution on the market specifically for children who needed a safe alternative to chewing on their hands, clothes, pencils, etc. This prism-shaped pendant is modeled after the same Grabber that you've come to know and love, only shaped into a fun and fashionable design for biting, chewing, and oral motor input.
    • Each pendant measures 3 inches in length and .5 inch in diameter (very similar in size as the extension of the Grabber).
    • The cord measures approximately 36 inches in length. If desired, you can shorten the cord by scooting the thread out of the clasp, retying the knot at a shorter length, and then trimming the excess thread.
    • Designed, manufactured, and assembled in the USA
    • Highly recommended for individuals who have Autism, sensory needs, anxiety, ADHD, etc.

    1. Perfect!

      Love the assortment of colors, prices and toughness levels.. only thing that is a little discerning is the shipping cost. The necklace was reasonably priced at $10 but shipping was half that. Would love to see shipping option between first class or priority so we have a choice cost-wise. Thank you!

    2. Amazing! Don't know how I lived without this before.

      I love this product. I am an 18 year old college student. Having this chew is helping me get control over my horrible nail biting habit, as well as offer me a great stress relief activity for during the day and or finals week. Before I used this, I had been chewing on everything. Toothpicks, gum, water bottles, plastic sometimes. Anything I could find. I honestly wish I had had one of these much much earlier. The results have been astounding to me. My nail biting has all but stopped, and I feel much less stress in general.

    3. Nice product

      My daughter was having problems with biting other children, so I got her this to give her somthing "safe" to bite instead. It has worked wonderfully and now she doesn't bite anything else

    4. krypto necklace

      I have a 23 year old daughter who I bought 2 0f these to try. One an xx tough and one x tough. We tried the teal one and she chewed trough it in 2 days. The lavender one is definitely tougher than the teal & I like having it around her neck so we can keep track of it.

    5. Stands the test!

      I have foster children who are chewers. They chewed up my house! I tried store bought biters and they didn't last. BUT...after buying this! This has held to the test! And my house remains in tact!!

    6. like it much better than other products

      My daughter has used this for about 2 weeks now, and it's awesome! She had another chewy necklace before, and managed to chew bits of it within a few days. The cord is a touch long for my small 7 year old, but we just put a knot in it in the morning.

    7. Great product

      My son likes chewing on his shirt collar. This was perfect b/c it hung down in the same area and he liked the texture. The only thing I didn't like was the breakaway feature. My son kept taking it off and losing it. I wish it had a stretchy rubber cord instead, but who knows if that would hold up?

    8. Cool design for son. Mom approved chewelry

      My son loves his teal gem shaped chewelry. It reminds him of his favorite block building video game. I like it because it saves him from chewing holes in his shirts, bitting his nails, and from chewing on unsafe objects. We are very happy with our order and will order more in the future.

    9. good qaulity

      my son has not used this one yet, rt now he is using the dino one. but we have used the brick one in the past and it worked very well as I'm sure this one will too

    10. Love it, really helps

      My 6yr old is on her 2nd Ark therapeutic necklace now. The first one lasted about a month. She chews throughout the day, every day. It has really helped her avoid chewing on her nails. It has caused her to be made fun of at school for chewing on it, but we found out there's other kids that have them too. I wish more parents knew about the usefulness of these. It's so much healthier than biting nails. We got the orange and purple. The orange one has already worn down in just a couple weeks.

    11. Stylish way to help

      I purchased one of these in the moderate range. My son loves it. He was chewing on the pencil grippers at school, chewing through pencils and even through electronic charging cables. I didn't know something like this existed and am grateful to have found it. He now only chews his necklace and doesn't chew everything else. This is such a great product and it holds up so well!

    12. Love the chewy

      Love them just need more colors in the XT and XXT options. My son wants one in every color but the softer ones wouldn't hold up.

    13. Loves it-Chewed it all Day the First Day!

      My 5 year old daughter has trichotillomania (pulls out her hair) and she also started biting her nails and has forever been putting foreign objects in her mouth. All of these things are related (body focused repetitive behaviors). So I thought I would try some chewelry to see if things improves. It's only been two days, but it's helped already! It's awesome! I think it's just what we needed! She can use it in class and not be disruptive. There are already 3 kids in her class that want a "chewy" (that's what she named it). We bought the smooth brick stick and this krypto-bite both in magenta/soft. She prefers the krypto-bite for sure because the brick in a little big for her to get it to her back molars easily. Also, you can shorten the necklace to custom fit your kiddo. It took me a day to realize this. It may be in the directions but I didn't read those. Good luck to all those families out there dealing with chewing related issues!!

    14. So Far So Good

      We have only had this product for couple of weeks and he does not use it constantly. only at school. So far it is holding up really well and my son has destroyed other chewies. So we are quite happy with it.

    15. Hooray for Ark, thank you!!!

      Ark's chew necklaces have turned my son's school day's around! His teacher says he is more focused than ever and generally has much better days than before he started wearing his "chewlery"!
      Thank you so much!!

    16. Thank you

      I am so thankful for the products this company makes for our special children. My son has an oral fixation habit and he would put just about anything in his mouth. The durability of the products we have gotten have been well worth it. He likes the look and I like that I don't have to worry about him tearing it apart in a day.

    17. Eh...

      The soft one is squeaky when you chew on it which causes sensory problems for me. the only nice thing about it is the cylindrical shape, but because of the squeakiness I can't enjoy it. The firmer ones aren't as squeaky but overall turned out to not be worth the price imo...

    18. Great product!

      I bought these for my 11 year old that was always chewing on something...pens, straws, her shirt. She likes the bright colors and that she can wear them all together or one at a time. Functional and stylish! :)

    19. Pretty good

      I messed up and bought 5 extra break away cords cause I didn't read it right but I wish they had packs of these available, even just 3 packs, that way if one gets lost somehow it's not as bad.

    20. Great Product!

      This necklace has been great for our 14 year old. He had been sucking on his fingers and this stopped immediately when he was given this necklace. We just started using chewables but our son chewed through them within days. This one is very strong. The length of it also stops him from chewing on the cord so the cord is holding up better as well.
