Silipints are made of 100% food-grade, FDA approved, platinum-cured silicone that is free of BPA, BPS and phthalates. They're durable, eco-friendly & will never wear out. Silipints will not break, crack, chip, dent, fade or scratch. Sized as a true American pint size, Silipint has thick and sturdy, yet squeezable walls that are not too squishy, and a grippy outer surface for extra safety. Avoid spills with the insane no-slip base. Silipints are safe for the microwave, freezer & more. Hand wash only. 16oz
