ARK's Krypto-Bite™ Chewable Tube Necklace

Other Details
  • Product Description

    A version of the popular Krypto-Bite that hangs horizontally instead|||ARK’s Krypto-Bite™ Chewable Tube Necklace is very similar to its popular gem-shaped cousin with one main difference:  instead of hanging vertically, it hangs horizontally.  In other words, the string goes through the whole pendant instead of just through the top.  Use this prism-shaped chew pendant as a safe, discreet, and stylish solution for anyone who needs to chew.  It's a great "chewelry" (chewable jewelry) oral sensory solution for both boys and girls, kids and adults to help calm, focus, and self-regulate.  Like all other ARK chewelry, it comes in 3 color-coded toughness levels:

    • Magenta or Red = Soft (very chewy), recommended for mild chewing only
    • Lime Green, Teal, or Black = XT (firmer, but still chewy), for mild to moderate chewing
    • Blue, Lavender, or Forest Green = XXT (the most firm), recommended for those who like to chew on firm / fairly rigid items.  This is also the longest lasting option for avid chewing. However, this is one of our smallest pendants (and it has a hole all the way through), so it is not the best (longest-lasting) option for avid chewing.  See below for more details.

    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 beaded chew necklace (like the fourth picture above, for example).  Color hues may vary slightly.  Each pendant measures about 2.2 inches wide and just under half an inch in diameter.

    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.  Please note:  this particular shape is not recommended for avid to aggressive chewing.  The longest lasting chewelry necklace is typically the original Krypto-Bite in XXT.  For the longest lasting chew tool overall, click here.





    • 15 years ago, our 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 about 2.2 inches long and just under half an inch in diameter (for reference, this is a bit smaller than the original Krypto-Bite if you have that one).
    • 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.
    • Get multiple necklaces and thread all of the pendants on one cord for a custom 'beaded' look.
    • Designed, manufactured, and assembled in the USA
    • Highly recommended for individuals who have Autism, sensory needs, anxiety, ADHD, etc.

    1. Perfect for my aggressive chewer!

      My 8-YO likes to chew on anything: his shirt, stuffed animals, whatever's around. We've tried many, many, MANY different chew necklaces, and the XXT line from Ark are the only ones that stand up to his constant, aggressive chewing. I like this model in particular because he likes to bend the chewies or shove them all into his mouth so he can chew with both sides of his mouth at once, and these tube-shaped ones stand up to that with little to no wear and tear.

      Note from ARK: I'm so glad it's been working for you guys! As a heads up to anyone reading this - usually our Dino-Bite or Super Star necklaces are the longest lasting necklace shape for aggressive chewing, with the Y-Chew XXT being the overall longest lasting chew. The Krypto-Bite Tube is one of our smallest chews, so in most cases it doesn't last as long as the other shapes with avid chewing.

    2. Thank You For Saving His Shirts!

      My son likes to chew the front of his shirts while he reads, does homework, etc. A lot of the fronts of his tees are misshapen and in bad shape because of this habit. I went looking for something to help him with his need to chew and found this site and this wonderful product.

      We cut the cord to the right length for him -- fits right under the neckband of his tees -- and he now chews on tube instead. I got him two different toughness levels to try out and he prefers the soft. The product is holding up well to his chewing and his new tees are not chewed up!

    3. Everyone is happy and our collars aren't frayed

      I opted to shorten the cord on this product so it was right beneath his collar.
      He's able to pull it up enough to chew when he needs to and its discrete enough to hide under his shirt and when he needs to chew.
      Love that ARK is US made!

    4. Good texture

      We purchased two different options for our son - this one wasn't a winner because he didn't like how the chewie was situated as he likes to use his back teeth. Texture was fine, cord was a bit long for him so I tied it off on the side.

    5. Perfect

      My son has ADHD and Sensory Processing Disorder. He has always chewed on his Left index finger. He absolutely loves this. It is just perfect. We have to get the XXT and it is very durable
