Okiyo Sora Bamboo Ball Pen

Bamboo has been used as a substitute for parts of this product which would usually be made from plastic or other synthetic materials. While it looks and feels like wood, the Okiyo Sora Ball Pen is made from bamboo, which is 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 be harder than oak, depending on the type and species. As bamboo is a natural material, there will be variation in the appearance in one product compared with the next or within similar items in a set.
