* Since the wood slices are cut from natural trees, our wood slices are not perfectly round. But we select suitable tree trunks before cutting so that the overall shape of the wood slices is as close to a circle as possible. * The normal static placement of wood slices will not cause the bark to fall off. Collision may cause slight damage to the bark. If you find that the bark has fallen off after unpacking and cannot be used, please contact us. * Thank you for choosing our brand, and we look forward to providing you with a delightful shopping experience!
