ARK's Krypto-Bite® Chewable Tube Necklace is very similar to its popular gem-shaped cousin with one main difference: instead of hanging vertically, this tube necklace 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. Toughness Guide:Standard - This is the softest level, recommended for mild chewers (those who do not chew through anything). XT / Medium Firm - This is the middle level. It's firmer, but still fairly chewy, recommended for moderate chewers. XXT / Very Firm - This is the toughest level. It still has some "chewability" to it, but it's fairly rigid / pretty firm. No chew tool is indestructible, but this is usually the longest lasting level for avid chewers.
