"The starfish chewy shape is a fun and fashionable shape that really blends in.   Starfish are made of BPA-free, phthalates-free, lead-free, PVC-free, non-toxic materials.  They are top rack dishwasher safe.  Give your child a better choice for chewing- save their fingernails, toys, pencils and clothing from being chewed.  Increase focus, attention, and allow your child to self regulate in a discreet manner.  Starfish also have a  breakaway clasp on the necklace. This chewy is not designed for strong chewers. Children should be monitored closely at all times and if the surface is broken or if pieces are chewed off, the chewy should be discarded and replaced immediately. If a child is under the age of 3, it is recommended that the parent wear the chewy necklace and offer it to their child when needed. "
