Drink up! And do so with a clear conscience. Our Bio Cup is totally constructed of biodegradable corn resin ... really! That means of course, that it's also made of a renewable resource. And ... it's made in the good ol' USA, FDA approved and safe to freeze for good measure. Included in the imprint area is our eco-friendly message: "Biodegradable Corn Resin". When you need cups, choose the Bio Cup and you'll be sending your message in an environmentally friendly way. We guarantee people will notice!
