These high quality products are a great way to get kids to learn about how to become environmentally conscious consumers. Made of corn, they are eco-friendly, non-toxic and biodegradable. Because they are made of 100% biolysis resin, they should be hand washed, and never used in a dishwasher, microwave, or for boiling liquids. Mother's Corn™ products are a fun and unique way to help kids set a good example of our commitment to a greener environment.
