I wish I had known about this site decades ago!! I’m an adult who chews on everything, pens, blankets,shirts, my arms and fingers are the worst for me. I wasn’t sure about the site or toughness I needed since this was my first time seeing anything like this that could possibly stop me from chewing everything in site. However, I had spent a long time reviewing other reviews and reading how to determine my toughness, I finally felt comfortable and decided to buy something. I know I needed something with a bit of texture, I think if it were smooth I would get bored with it. Therefore, I chose the star wand with standard toughness. I was really worried being an adult that I might bite once and it wouldn’t crumble to pieces. I still decided standard toughness. When I received the package, it was packed nicely and also came with a pamphlet. Days later I’m still chewing my star wand and to my surprise it has not broken, torn, or worn out anywhere. I’m so Happy that I have something to curb my chewing habits. The standard toughness is just right for me. Not to soft and not to hard, it’s Perfect!!! I will be reordering more as I need to, only because I like variety, not cause my star wand is worn out, I think it’ll be a long time before that happens. It is very durable, there are no plastic or rubber smells to the wand. Like I said, wish I knew about this site before. But now I do and I’m very grateful it exists for people like me who need to chew.
