Our Chewy teethers make fantastic gifts for teething babies. One side of the car is smooth, and the reverse has lots of ‘bumps’, creating a textured surface to aid with teething and keep little ones amused. The material used is of a gummy texture and is made from BPA/PVC free silicone, (also free from Phthalates). It is same material used in many bottle teats, dummies and high street teethers. It is easy to clean, stylish and very functional!
