These are replacement sleeves specifically for the Kirakku collar, from the well-known Eriyoshi. They have been used twice and home-cleaned. The Emilio Pucci-like textile has a retro-modern feel and looks stylish when glimpsed. They look great paired with subdued kimonos. Retail price: 9900 yen. Although they are in good condition, they are USED, so please check the images for the condition. The Velcro is also clean. These are semi-wireless, smooth, thin polyester. They feel good to the touch. Please refrain from purchasing if you are overly concerned about condition.
