Smiles by Jo products are specially designed with functionality, affordability and most importantly safety in mind. They use a combination of silicone, beech wood and a healthy dose of handcrafted love. We always ensure all materials used are tested for safety to ensure they’re of top quality. This item also has the ability to be engraved, turning it from a functional toy, to a keepsake to treasure for years to come. Put simply, they look good, feel good, sound good, are super safe, and are handcrafted just for YOU!
