With 4 differently textured extensions to chew on, you'll never get bored.  Rotate between circular bumps, zigzag bumps, ribs, and lines – a sensory seeker's dream.  Each extension is long enough to reach the back molars for proprioceptive input to the jaw and masseter muscle.

Not just a chew, the Tetra-Bite® also makes a great hand fidget!  Put your pointer finger inside the hole and use your other hand to make it spin on your finger.  Or, hold it in both hands by the circular extensions and twist to make it spin.

Made in the USA, it's a safe outlet for anyone who needs to chew, and an effective way to help calm, self-regulate, and focus.
Like all other ARK chews, it comes in 3 color-coded toughness levels:

Standard = the softest option (most chewable level) recommended for mild chewing
Medium = firmer, but still chewy, for light to moderate chewing
Strong = the most firm, for those who like to chew on fairly firm / hard items
This is also the longest lasting level for eager chewing.

Caution: This product is not a toy. Recommended for children 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, regularly inspect the chew, and replace if necessary if the item shows signs of wear and tear.
