Our bowls are uniquely manufactured and are innovative in design. Keeping to our mission of sourcing and wholly manufacturing in the USA, we discovered rice hulls. Rice hulls are the coatings of seeds, or grains, of rice. They are a class A thermal insulating material because they are difficult to burn and less likely to allow moisture to propagate mold or fungi. We use domestic rice hulls grown in Arkansas. Using rice hulls makes our product 30% lighter in weight than the equivalent bamboo/melamine bowls, contain 30% renewable content and are formaldehyde free.
