Compression leggings to increase calorie burning efficiency, size L, black. - Color: Black - Size: L - Features: Includes a chart indicating the best times for calorie burning. Thank you for viewing. This is an authentic product. It is a Slim Feather L size. I am 163cm tall and weigh 65kg, and it fit well. It straightens your back and is effective in improving rounded shoulders, and you can feel a warming, burning sensation. I bought a set of 3, but one is enough, so I am selling the extra ones. One for 3000 yen Two for 5800 yen I will consider a small discount. Thank you very much ^ - ^
