Chewer: Heavy Our star dog tag sensory chew necklace is fun while also calming and soothing for the oral sensory seekers who like something firm to chew. We have paired this piece with a 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 wearers 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 dog tag is 50 mm long, 30 mm wide and is 6 mm thick.
