These are natural black, footed shell buttons. As the shells are a natural material, there may be some irregularities. The foot on the back is plastic. There may be some traces of adhesive or stains from long-term storage. I will wrap them in bubble wrap, but please understand that damage during shipping is unavoidable. The adhesive may come off due to strong stress during use. Please be careful. Anonymous delivery. I have other items for sale. Search for #crescent釦素材.
