This is a replacement sleeve for the Erihide "Kirakku" fake undergarment. I purchased it from Rakuten Ichiba's "Erihide" for 5500 yen. I am selling it because I have a similar replacement sleeve and haven't had a chance to use it. I used it once for a dressing practice, but I haven't gone out wearing it. Below is the manufacturer's product description ↓ These sleeves feature a blue-gray base color with a "kuwai" (arrowhead) pattern. They are perfect for komon and tsumugi. They are half-lined, so you can use them with both lined and unlined kimonos. Made of polyester, so you can wash them in your home washing machine. There are two Velcro fasteners on the front and two on the back, which can be attached to the dedicated "Kirakku" fake undergarment. Product Details: Material: 100% Polyester Sleeve Length: 1 shaku 3 sun (49cm) Sleeve Width: 32cm Velcro Position: 2cm and 14.5cm from the top (2 places on the front and 2 on the back) Velcro Size: Length/2.5cm x Width/4cm Suitable Kimono: Casual kimonos such as komon and tsumugi Wearing Season: October to May (lined season), June and September (unlined season) There are no noticeable stains, but please understand that this is a used item that has been opened. *Please note that we cannot negotiate the price.
