ARK's Y Tips are a great complement to any oral motor tool bag. Similar to the shape of the Y-Chew but fashioned into tip attachments for the Z-Vibe®, these tips are specially designed for jaw grading, jaw stability, lip closure, and sensory input.

Each arm has a different thickness. The orange tip's arms are .125" and .2" thick. The magenta tip's arms are .3" and .4" thick. And the teal tip's arms are .5" and .6" thick. 

These Y tips are firm but not 100% rigid for good resistance during jaw grading practice, and each tip has gentle sensory bumps to grip the teeth.
