I've used these a few times, but I prefer tights, so I haven't worn them and have been storing them. Would you like to try them? *No box included.* ◆ Cooling airy design, beauty leg socks specifically for sleeping ◆ Cooling sensation: Uses "BREEZE," a contact-cooling material that provides a -4 degree Celsius cooling effect, offering a refreshing and comfortable feel from the moment you put them on. ◆ Breathable mesh knit. Notes: Stored at home. Please understand that these are used items before purchasing.
