I'm selling a two-box set of the item I purchased. Unopened. Product Description "Megurhythm Steam Heat Patch" is a heat patch that you apply directly to areas with stiffness or fatigue. While enveloped in the pleasant warmth of steam, it improves blood circulation in the affected area, relieving stiffness and fatigue. ◇The Secret to Soothing Relief◇ ●Steam Heat, Approximately 40℃ Comfortable temperature lasts for 5-8 hours. The gentle steam heat warms deep into the affected area. The steam emitted from the patch is so fine it's invisible, gentle on the skin, and won't wet your clothes. ●Thin sheet that doesn't show through your clothes The sheet fits snugly against the skin and is unlikely to peel off even when you move. It's easy to apply to joints, neck, and shoulders, and it's thin, so it's not noticeable under clothing. ◇Why does heat work?◇ Long hours of computer work or standing... When the body remains tense, blood circulation worsens, and pain and fatigue-causing substances tend to accumulate. Warming the affected area deeply improves blood circulation, making it easier for accumulated pain-causing substances to be flushed away. ◇Six Effects of Heat◇ ●Improves blood circulation ●Relieves muscle stiffness ●Relieves muscle fatigue ●Activates the function of the stomach and intestines ●Relieves pain from neuralgia and muscle pain ●Recovers from fatigue
