Our Donut Sensory Necklace can be worn by anyone. It is a playful piece of jewellery that mum can wear and bub can play with safely, or it’s a fun necklace for kids to wear. The breakaway clasp improves safety by breaking open when large force is applied to it and the cord offers a soft non scratchy finish which will not irritate the wearers skin. The donuts are 20mm in diameter and is 8mm high. Chewer - Light
