Bumkins Jelly Silicone Collection is made from 100% food-safe, LFGB-grade silicone, which is tested to higher standards than regular FDA-grade silicone. Because of this, LFGB-grade silicone inherently uses less additives or fillers, is less likely to impact the smell or taste of food, and has a higher durability compared to FDA-grade silicone, resulting in a more premium product. You can read more about the differences between the two grades here.
