These are attachable sleeves purchased from Catherine Cottage. The color is lilac. It's a mature and elegant color (^^) The original price, including shipping, was 2720 yen. I bought them for my child's piano recital but didn't use them, so they are unused and brand new. I haven't even washed them. The recital only happens once every two years, and I don't think I'll use them next time, so I'd be happy if I could pass them on in their beautiful condition♬ Here's the official description☺︎ Add attachable sleeves for a rich look!
