Ashi Tsura Night Nighttime Calf Supporter Unisex, 1 pair, Size M This nighttime calf supporter seems to reduce leg fatigue and promote blood circulation. I received this as a gift, but I'm selling it because I don't use it. I opened the outer box to list it, but the inner packaging is unopened. Please refrain from purchasing if you are concerned about the condition, as it has been stored at home. Thank you for looking.
