Produced by Yuumi Kashiki, a charismatic body trainer. Instant improvement of posture and style through gently drawing the shoulder blades together. Also, slims down those bothersome upper arms. Purchased in December from Dinos. One is brand new and unused. One was worn once, but the size didn't fit, so I'm selling it. It has been washed, but please refrain from purchasing if you are concerned. Thank you very much. m(_ _)m Product: Curvy Slim Arm Size: L-LL Color: Black Upper Arm Circumference: 26-33 cm Shoulder Width: 39-49 cm
