True to its name, this Bamboo Tornado pen's handle is made entirely out of bamboo. Not only it looks cool, because it's made from bamboo, it is environmentally sustainable too since bamboo is a renewable resource that is both beautiful and durable. When you purchase a Bamboo Tornado pen, you are also helping the Arbor Day Foundation to help rescue 250 square feet of rain forest and the habitat it protects. This pen gets our two thumbs up!
