hello Kate, thank you very much for your sample order for 1pc first, just like before we explained, if it is all made of 100% bamboo powder, it cannot form a barrel shape, there must be other materials mixed with the bamboo, but all are environmentally friendly materials , 30% melamine, 20% corn starch, 50% bamboo fiber, this ratio is the optimal ratio obtained after long-term technical research, it can be molded, the surface of the product itself is very good of this kind optimal ratio, and the use functions of the product are relatively good.Also we supplied you our other customers link which sell well on Amazon Platform ,whose material is same as the one sent to you. Could you pls. kindly consider again for the item ? Thank you.
