The Cool Cord is an innovative product from Stacy's Sensory Solutions that is a wonderful solution for those that need to chew on collars or sleeves. The cord is made from strips of cotton jersey with 5% lycra for a little stretch. They are completely washable/dryable and very durable.
Their similarity to necklaces athletes sometimes wear helps with the "cool" factor. The Cool Cord length is 16". If a Chewable is attached to the Cool Cord, the length will be 24".
