The Santeco Como is a 500 ml kids' tumbler with a Tritan body and a Unicorn print, sized for school lunch boxes and outings. Tritan is a tough, clear, BPA-free plastic that does not shatter like glass. The supplier lists it as a vacuum (insulated) tumbler. We could not find the maker's detailed specifications for this exact model, so only the details in the name are given here: capacity, Tritan construction and the Unicorn design.
