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