High-neck long sleeve Innerwear Size 170 I bought this for skiing but I'm selling it because I didn't use it. There is no 170 size option for kids' innerwear, so I'm listing it as size 160. Please refrain from purchasing if you are sensitive to items stored at home, although there are no pets or smokers. No price reduction, please. Simple packaging. To ensure prompt shipping, I may change the shipping method from Rakuraku Mercari Delivery to Yu-Yu Mercari Delivery, so please be aware of this. #Underwear #Innerwear #Skiing #Undergarments #Heattech #ThermosFact
