These are Grant E One's limited edition knee-high socks with lace trim. They have compression like regular socks and use Far Infrared Ray (FIR) technology to prevent swelling and help slim your legs. I've only worn them once. There's a slight fraying on the inside, so I'm offering them at a reduced price. Please understand that these have been stored at home. Size M: 23-24.5 cm Original price: 7800 yen - Color: Black - Design: Lace - Material: Stretch - Type: Knee-high socks Thank you for looking. Grant E One's
