This product is designed as the perfect home for the dish soap block, but can be used for any soap bars. Moso bamboo, known as the giant bamboo or timber bamboo, has been used for centuries to fashion buildings, flooring and culinary tools. Place in an area where it can drain or elevate to keep out of standing water. It will need replacement with time. Each soap dish typically lasts several months but this will vary depending on your placement, if you allow it to sit in water and your climate and humidity. Bamboo naturally biodegrades and this item can be composted at end of life.
