These wonderful vintage buttons are rather unusual in shape and are in excellent condition. They are a medium olive green and have a metal loop shank on the back. I believe these are a rectangular variation of the better known cylindrical "bench coat" button. I believe they are circa 1930's. The buttons measure 1 7/16" long and are about 3/8" thick.
*Please Note: My vintage buttons are in " as found " condition and have not been washed. I only brush or wipe surface dust from them. I'll let you decide how you want to clean them.
