A charming and beautifully presented bamboo gift set, which offers more than meets the eye. While it looks and feels like wood, bamboo is actually a type of grass. It grows incredibly fast and can reach full size in a fraction of the time it takes for a tree to grow. This makes it a highly sustainable material, which can actually be harder than oak, depending on the type and species. Bamboo has been used as a substitute for parts of this product which would usually be made from plastic or other synthetic materials that are harmful to our environment.
