I bought these at Shimamura last year, but I couldn't quite figure out how to use them. I wore the black ones twice. I'd like to sell the black and white set together. They are about 16 cm long. They flare out from about halfway down. If anyone would like to use them. A set of frilled lace detachable sleeves, available in white and black. - Color: White and Black - Material: Lace - Style: Frilled Cuffs - Quantity: Set of 4 - Design: Lace detailing with scalloped edges Thank you for looking.
