Review on 🌱 STCA 8586 Eco-friendly Stacking Cups by Green Toys by Matthew Sutton

We love these stackable mugs! The packaging is made of high-quality recyclable cardboard. I noticed that the side of the packaging says the volume of each cup corresponds to the cup number! For example, filling glass 4 and glass 2 with water equals the volume of glass 6, and so on! I'm always looking for real learning apps for my kids so this was a very pleasant surprise. Mug made of very durable plastic. They stack easily and fit well. My 9 month old plays with mugs both in and out of the tub. My 5 year old loves experimenting with the simple math mentioned above. I am very happy with my purchase and look forward to more Green Toys products.
