Silicone beads – 12 mm – oval/disc/spacer Size: 12 mm BPA‑free CE‑certified 100 % child‑safe These beads are often used as a spacer between (silicone) letter beads. The beads are usually square, and when placed side by side they form a solid, stiff surface. This does not move easily. With oval spacers in between jij maintain a more flexible pacifier chain or a teething ring that stays nicely round. Without these spacers jij will end up with a straight segment in your teething ring.
