Replacement sleeves for Kiraku. Purchased online and used only once. In excellent condition with no signs of wear. These sleeves feature a charming gradient from cherry blossom pink to a pale lavender color. I don't believe they are from ERIFU. I bought them from a shop in Kyoto that specializes in making Kiraku-sized items, but I've forgotten the shop name and don't have the details. The material is also a mystery. It's a more substantial and crisp material than ERIFU's polyester, with a visible texture, so please refer to the images. Han-muso (half-lined). Not flimsy. For those who understand that this is a home-stored item.
