Dome-shaped light weight metal buttons. There are 3 different sizes in this pack. They are all pictured. These are vintage so a bit beaten up but in good condition.
metal shank for sewing or stringing on cord.
A note about attaching these buttons. No joke it can be a PITA if you try sewing them on individually. So what to do? String them onto a cord, yard, trim, or anything you can think of and sew them down.
