[Opened, Unused] COGIT Wave Upper Arm Sauna ★ When shipping, the box will be folded along the creases and sent via post. Product Description This is an upper arm sauna suit that tightens the sagging upper arms and shoulders with its uneven wave design. The uneven inner surface that touches the skin stimulates the skin with movement. The air layer in the recesses increases the sauna effect with its high insulation, making it more effective when worn while doing housework or sports. Also, the recesses make it less likely to get stuffy even when sweating, providing a comfortable fit. Using thin rubber and a three-dimensional cut, it fits perfectly with any movement. Recommended for those who want to stylishly wear sleeveless dresses.
