This is a hair wig, an original from Kateigaho Kimono Salon. It easily adds volume and creates up-dos, suitable for both kimono and Western clothing. The original price was 33,000 yen, and it comes with the box, a brush and comb, and instructions. The color is "natural black." It has pins that can be secured at the back, making it easy to attach. It has only been tried on once and is practically unused. Here's a video on how to use it: https://www.kateigaho.com/article/detail/146711
