Uses Toray Siljely Washable Hermite Nagajuban (under-kimono slip) 100% Polyester 12.0m This is a new, unused item, but due to long-term storage, there may be age-related deterioration, sunburn, stains, mold, etc. It also has an old smell. As this is a very old item, please refrain from bidding if you are even slightly concerned. Please inquire in advance if you have any concerns. However, I do not have detailed knowledge about kimonos. Those who do not promptly provide a receipt evaluation will be blocked. A8
