Thank you for looking! Both of my children loved these, and they enjoyed using them in various ways for a long time, from infancy to toddlerhood. These are recommended for educational play in various areas such as colors, sizes, shapes, and numbers. <Toyroyal Stacking Cups> These rounded cups with a bunny rattle are easy for babies to stack. We also used them as plates for pretend play. <KIDSTHRILL Rainbow Stacking Cups> Purchased at Toys "R" Us overseas. We used these as bath toys. The bottoms of the cups have animal illustrations, which were good for learning names. We played games with color and animal quizzes in both Japanese and English. There is some wear and tear, so please check the condition in the photos.
