Great used  condition. Unsure of the material used in these items. Maybe some kind of resin or plastic. I like the big ones for changing out on a coat or jacket. Vintage buttons change out on an old jacket, tweed, and blazer for giving it a different look.  Smaller ones for doll dresses, blouse, or spice up a t-shirt, and sew around the collar. Glue to a tack and give your cork board an artsy look. There are so many ways to use buttons. Bags of buttons are heavy. If you want to buy more than one item, I can send an invoice to reduce shipping.
