The U Tube Sensory Necklace is soft, flexible, and chewy. Its versatile design will appeal to many different types of chewers. 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.
