1 1/2" Birch Perch 9"

My quaker lovess peeling off bark from perches so this perch became one of his favs really fast. It was interesting to watch him figure it out because the bark on this wood is different from other woods (it peels off like paper). Once he figured it out, he's been having a blast. I wish birch bark was sold separately as well cuz I think I need a ton more ??. Thank you!
