Our Aspen Wood Business Card Holder and Pen/Pencil Cup are made out of aspen logs that have seasoned naturally in the forests of the Colorado Rocky Mountains. Collected from ranches, as a way to thin out tender, only dead, dry and seasoned wood is used in each or our pieces. The wood is then debarked, sanded, cut and shaped into a unique piece of functional art for you to enjoy. Each piece is unique. Colors and natural characteristics in the wood will vary.
