【Product Description】 SLIM FEATHER Upper Arm Compression Innerwear (1 piece, unopened) This is the "Slim Feather" upper arm shaper, a hot topic on social media and elsewhere. I purchased a set of 2, but one was enough, so I am selling this one, which is new and unopened. This innerwear tightens your upper arms just by putting it on and also supports your posture. ■Brand VIRNAS Co., Ltd. / Slim Feather ■Size M size • Sleeve Length: 24-30cm • Shoulder Width: 36-43cm ■Color Black ■Material • Nylon 90% • Polyurethane 10% ■Condition • New, Unopened • In beautiful condition, just arrived from the official website.
