Guess what these bowls are made of? If you thought cornstarch or sugarcane you are correct! Our set of eco-friendly bowls is our latest contribution to creating a more sustainable future through innovative products. Made of PLA, a plant-based bioplastic free of toxic materials that adds resistance and a longer life span to products. If all these features seem very complicated, know that for your kids it'll be just another bowl they use, but one that can do good to the planet.
