This is the Green Toys Stacking Cups 6-Piece Set — six graduated cups in rainbow colors that nest inside each other for storage and stack on top of each other to build a tower. The classic first-year learning toy: babies and toddlers learn size order, color, and balance by trying to get the tower to stand without tipping.
Each cup has a cutout in the bottom, so stacked cups become a water-play tool — scoop, pour, and cascade water from one cup to the next in the tub or kiddie pool. That turns the same six cups into three toys: stack them, nest them, or pour water through them. Dishwasher-safe, BPA/PVC/phthalate-free, sized for baby and toddler hands.
Green Toys is made in California from 100% recycled milk jugs and other food-grade HDPE plastic. The company was founded in Mill Valley in 2007 on the idea that kids’ toys could be manufactured domestically from recycled American material — no BPA, no PVC, no phthalates, no external coatings. Every toy is dishwasher-safe and shipped in recycled, recyclable packaging printed with soy-based inks.
