it is made of SAN, which has excellent clarity and durability, and holds 14-1/2 ounces. Kids love eating with their favorite characters--the fun artwork is fully wrapped, visible from any seat, and filled with bold personality. The convenient cone shape is easy to hold for small hands, and the tapered sides mean that multiple tumblers stack together for space-saving storage when it is time to clean up. This tumbler is completely BPA free, because safety is important. You can put it in the dishwasher, but do not microwave. Rmended for children ages 3 and up.
