Six graduated cups offer dozens of possibilities for bath and play. Scoop and pour water, build towers by turning them upside down, or simply sort by size or color.

For example, filling cups 1 and 2 corresponds to the volume of cup 3. Made in the USA from 100% recycled plastic from milk jugs, saving energy and reducing greenhouse gas emissions.
