Thank you for viewing. This is highly popular recovery wear from Workman. MEDIHEAL is fatigue-reducing wear that has been registered as general medical equipment. The high-purity ceramics, which are incorporated into the fibers using unique technology, radiate far-infrared rays released from the body. This promotes blood circulation, creating an environment that alleviates fatigue. Currently, it is difficult to obtain this size and color in stores, so it is recommended for those looking for it. ・Brand: WORKMAN ・Item: MEDIHEAL ROOM Long Sleeve Shirt ・Color: Black ・Size: M ・Condition: Brand new, unused, unopened Instant purchase is welcome. Thank you!
