Tsumami Zaiku Hair Accessories ★ Not for Resale ★ Hello. Thank you for viewing my items from among many others. These are handmade using domestically produced rayon koshi-chirimmen, sourced from a chirimen specialty store. Chirimen is sensitive to water, so please handle with care. Avoid use on rainy or snowy days. Also, applying excessive force may cause deformation. All pieces are finished with 5cm U-pins. These are handmade by an amateur as a hobby, so there may be some glue overflow or slight imperfections. I would appreciate it if you could understand this before purchasing. Thank you very much. m(__)m Please read my profile.
