This new innovative product from Stacy's Sensory Solutions is a wonderful solution for those that need to chew on collars or sleeves. The chunky cord (1/2") is made from strips of cotton jersey with 5% lycra for a little stretch. They are completely washable/dryable and very durable. These cool cords necklaces come with a silicone bead attached (color preference for bead can be stated in comments, otherwise, color will be random). Cool cord necklaces are 16" but can be modified to fit your needs.
Cool Cords are available for pick-up in the Dallas, TX, area to avoid shipping costs.
