This is a set of 16 buttons cut from a Birch tree branch. They've all been sanded smooth with the beautiful white Birch bark still intact. They're 3/4" wide and 3/16" thick. I've rubbed them each with a Beeswax and Orange Oil conditioner, then sealed them with polycrylic. They're perfect as functional buttons, or to use as accent pieces on many different craft projects!
