This brush is made with a bamboo handle, which provides both a low impact environmental effect and What is special about bamboo? Bamboo is not a tree but grass that grows in almost every tropical climate. While it takes a tree many years to mature, some varieties of bamboo can grow a foot per day, so there is no danger of depopulating a forest of bamboo plants. The ferule is also ecologically thoughtful, being made from recycled aluminum. The brushes come packaged in a low impact, bio-degradable sleeve. The synthetic taklon bristles are soft, luxurious and appeal to even the most meticulous makeup artists and brush snobs (ye you).
