There are four buttonholes, two at the top and two at the bottom. Please check the images. Please be sure to read the profile. I purchased these items from overseas or domestic handmade material stores, vintage shops, and flea market apps. I enjoy making handicrafts and have bought a lot of materials, so I am selling the ones I 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 my profile. Please apply for combined shipping instead of creating a dedicated page ( .ˬ.)" If you are unsure of the combined price, please comment. Some items may have scratches or stains from the time of purchase. I will describe any noticeable ones in detail, but this is entirely based on my personal opinion. I have taken photos of the actual items I will send, so please check them carefully before purchasing. Size: 40mm
