High-quality buttons, deadstock. 15-20mm. They're cute as they are, used in accessories, etc. The colors may not be exactly the same as in the images. Please understand this before purchasing. I don't think the backs are metal. Although unused, there may be small scratches due to their age. Please check the photos carefully before purchasing. Shipping will be via standard mail. Please be aware that it will take a considerable amount of time. *If paying at a convenience store or ATM, please let me know your expected payment date. *I will create a dedicated listing for combined purchases, but only for those who can purchase on the same day, or at the latest, the next day.
