Product Description
This listing is for 1 teal pendant on a breakaway cord. Made in the USA, ARK's Krypto-Bite Chewable Gem Necklace provides a safe, wearable, and discrete 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 chewable jewelry 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.
This teal pendant is "Xtra Tough", recommended for mild to moderate chewers. Tougher and softer versions are available separately.
Designed, manufactured, and assembled in the USA by ARK Therapeutic. Medical grade. NO lead, phthalates, PVC, BPA, or latex.
CAUTION: This product is NOT a toy - use should be supervised at all times. The clasp and cord are NOT intended for chewing. Only the pendant is for chewing. Contains small parts and a cord that may pose a choking hazard. Not recommended for children under 5 years. Although these chew tools are sturdy, 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 for avid chewing, see ARK’s Y-Chew XXT.

- Reviewed in the United States on November 10, 2023This teal one is the perfect mid between the hard purple and the super squishy magenta. My daughter got this one last September right before our cross country move from California to Kentucky and it lasted just about a year before showing wear. She favors this one over the others and she wears it constantly. I know it's not recommend to leave it on all the time but for her it's necessary. I shorted the string so it doesn't hang and touch things while she is out or become a choking hazard while playing and I tie the knots on both sides to keep it centered so the weight of it keeps it from moving around and her chewing the safety clasp. The clasp on the first crystal was completely destroyed in just a few days from her chewing it since the crystal would migrate to the back and float around and after being chewed up it didn't work to keep it secure so I had to keep it knotted in the back so it wouldn't fall off. The side knots work great for keeping it centered though. She's had this new one for about a month now and with making the side knots she hasn't tried to bite the plastic and she can use it as a safety clasp. I don't know why the newer one is smaller, maybe from her just chewing so much on the first one and it's full of drool lol Im not sure but it's still great. ARK is by far our favorite brand for our sensory seeking just turned 5 yo daughter and this crystal shaped one is cute enough to look like just a fun necklace and not a chew toy on a string that looks like a giant teether. We have tried a few different reputable companies for oral chewers and this one is awesome.

- Reviewed in the United States on January 17, 2025My kindergartner loves to chew and without anything she’ll wear her fingernails down right quick. We had some others from another brand that were also softer material, and the entire ten pack was obliterated within a couple months. Went with the XT which seems like a good mix between softness and toughness. It’s long too so she’ll just chew on it all day with those back teeth, no problem
- Reviewed in the United States on August 23, 2016I love this so much. I am a 28 year old who is not diagnosed with any kind of oral sensory needs, but I do have diagnosed anxiety which results in biting my nails, skin picking, peeling nail polish, chewing a blanket if its available. Now that I am starting graduate school, I needed a more sociably acceptable way to manage my nerves and this hit the spot. I chew on it when driving. It is recommended to put in your back teeth, but as a nail biter I find it most effective in the front, especially when rubbed against the angled/pointed tip. I have already bitten a small hole in it once, but it is not noticeable. I will say this necklace was larger than I thought it would, so though you can hide it in your shirt - it is pretty noticeable when chewing - about the length of my ring finger. The only thing I would change is the firmness level I ordered, but that was because I didn't know what to look for. Strong product. No weird taste. Color is accurate. Would buy again and have already recommended it to friends.

- Reviewed in the United States on December 17, 2016My daughter, 7, chews on her fingernails, hair, clothing, etc. all day long so I bought this for her to chew on instead. It has a nice bounce to it but seems tough enough to last for a while. I also purchased the Bite Sabers for my boys but they are much harder than this, even in the same firmness, they don't have any bounce to them.
- Reviewed in the United States on April 1, 2024So far so good, actually purchased a second. This company was recommended to us by our speech and physical therapist. I am very happy with the quality. Son is 3 and this is the perfect size for him to chew using his back teeth and not choke himself.

- Reviewed in the United States on June 30, 2020We got this for my daughter because she chews her nails. This has helped transfer her chewing energy! I was worried about the durability because she can chew through anything but this has held up wonderfully! The string is also durable. Great product!

5.0 out of 5 stars 8 year old loves it!
My 8 year old would always have her fingers, hair or clothing in her mouth, especially when concentrating on school work and such. With this necklace, she's proud to wear it like jewelry and I can wipe it down and I know she's not putting germs from everything she's touched in her mouth.
- Warbs_lReviewed in the United Kingdom on November 2, 2019
5.0 out of 5 stars Good strong chew
The best chew toys I have found for sensory seekers with a strong bite. We have tried many many chews before which have been bitten through almost straight away, we are over a month in and no signs of wear yet. Also impeccable service
