Snap buttons purchased through mail order about 15 years ago. Not sold individually. These were purchased as a lucky bag, so the details of each button are unknown. I don't know if they've been used or if all the matching parts are the same number. Visually, there are no signs of rust or damage. If you'd like to see a close-up of a specific part, please let me know and I'll add photos. #handmade #crafts #materials
