Looking for a stylish and functional way to chew? The ARK Krypto-Bite Chewable Gem Necklace provides calming, focusing, and soothing oral input—all while looking great. With a name inspired by the Greek word “kryptos” meaning hidden or concealed, it’s one of the most discreet and versatile chew necklaces. Designed to reach the back molars, the 3” long crystal pendant is a go-to chew for kids and adults. Whether you're at school, work, or just need a moment to self-regulate, the Krypto-Bite is a safe and effective solution. Like all ARK chewelry, it’s available in 3 color-coded toughness levels to suit all chewing needs: Standard: The softest level - recommended for mild chewers who do not chew through anything. XT / Medium Firm: The middle "Xtra Tough" level is firmer, but still fairly chewy - recommended for moderate chewers. XXT / Very Firm: The “Xtra Xtra Tough” level is very firm and durable - recommended as the longest lasting level for avid chewers. WARNING: This product is not a toy. The clasp and cord are not intended for chewing. Contains small parts that may pose a choking hazard. Not recommended for children under 5 years. Although these chew tools are made out of sturdy, medical grade materials, they are not indestructible. Some individuals (particularly those with heavy oral needs and aggressive biting/chewing) may be able to damage the tools. Please supervise at all times and replace if necessary when the item shows signs of wear and tear.
