Our Chewy teethers make fantastic gifts for teething babies. The sides of the butterfly teethers are covered in tiny heart shaped bumps, making them perfect for keeping little gums 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!
