All materials are FDA approved and RoHS Compliant, meaning they are BPA, PVC and Phthalate free! We work hard to use only the best materials in our products. The Snack Spinner is made primarily from plastic #5 (considered one of the safest polymers for humans since it doesn’t leach chemicals even at high temperatures). Inside the Button mechanism we use a very stiff, food-safe plastic called POM and a Stainless Steel spring.
