Our coconut shells are made by hand from real coconuts. The raw materials for this are obtained from waste. The bowls are then polished and refined with organic coconut oil. No artificial paints or adhesives are used and the shells are 100% natural. As each coconut shell is handmade unique, they may vary slightly in color and shape. The bowls are natural products, so the bowl may change color a little depending on what is being prepared in it. That's why we recommend cleaning them with water and a little detergent after use. To keep your coconut bowl looking good for as long as possible, it should not be placed in the oven, microwave, refrigerator or dishwasher.
