Buttonhole, one at the top, can also be used as a charm. Please be sure to read the profile. Purchased from overseas or domestic handmade material stores, vintage shops, and flea market apps. I enjoy making handicrafts and am selling items that I have purchased a lot of but can't use up. I do not accept requests for handmade processing. If you are concerned about the product or are looking for a perfect item, please refrain from purchasing. Discounts are available for bulk purchases; details are listed in the profile. Please apply for combined shipping instead of creating a dedicated page ( .ˬ.)" If you are unsure of the combined amount, please comment. Some items have scratches or stains from the time of purchase. I will describe noticeable ones in detail, but it is entirely based on my subjective opinion. I have photographed the actual items I will be sending, so please check them carefully before purchasing. Size: Approximately 24mm
