Silipints are made 100% food grade silicone. Hang on while we nerd out. Silicone consists of four, readily available and abundant elements: oxygen, carbon, hydrogen, and silicon – the second-most abundant element in the earth's crust. In addition to being completely non-toxic (no BPA’s or petroleum products here), silicone is an incredibly durable, versatile, and environmentally conscious material. Silicone is also heat-safe, cold-safe, insulative, and easy to clean. Bendable, flexible, and unbreakable, we think it’s the perfect material for any drinking cup.
