Chewer: Medium The U Tube Sensory Necklace is soft, flexible, and chewy. Its’ versatile design will appeal to many different types of chewers. The additional beads add another texture and a shape that can be easily ground by the molars when stress relief is needed. We have paired the necklace with a matching breakaway clasp and strung it on a soft cord. The breakaway clasp improves safety by breaking open when large force is applied to it and the cord offers a soft non scratchy finish which will not irritate the wearer’s skin. The round edges of this shape make it easy for the wearer to work it to the back of the mouth between the molars for maximum vestibular stimulation and the calming effect that it can bring. The U Tube is 160mm long and has a 12mm width.
