This is a naturally hollow white birch bark tube. It is great for weddings, crafts, taxidermy, landscaping, or placed with plants. It could even be a condo to one of your 8 legged friends in a vivarium. This piece was gathered from downed birch trees and found on my own birch tree haven in North Central Wisconsin. The piece is approximately 24 inches long by 8 inches wide and 6 inches thick.
