I use 38mm walnut buttons. The fabric is made from recycled kimono fabric. The hair tie can be easily replaced. It can be matched with Western clothes. Of course, it also goes well with kimonos, but it's recommended for more casual kimonos, such as yukata or hakama worn at graduation ceremonies, rather than formal wear like furisode or tomesode. ✨ I make them with care, but they are handmade by an amateur. Thank you for your understanding.
