Dear little.t, Thank you for viewing. These were made from scraps of kimono fabric. The material is mostly silk, but I think some synthetic fibers are also mixed in. Please feel free to add your favorite beads, etc., to arrange them. I try to make them carefully, but since they are handmade by an amateur, the shapes are not as uniform as those of mass-produced products. I would appreciate it if you could understand this. Please enjoy them by加工ing them into snap clips, barrettes, brooches, or whatever you like. Thank you very much. *To those considering an order* Thank you for considering an order. We have a dedicated order page, so please take a look at it and consider your order.
