Uniqlo Heattech, Extra Warm. Size is M. I bought it new, but it wasn't necessary for me, so I ended up not using it. It's new and unused, but please check the condition in the photos and only purchase if you are satisfied. May switch between Rakuraku Mercari and Yu-yu Mercari shipping. 【Notes】 * Cancellations after purchase are not accepted. Also, to prevent product substitution, returns are not accepted. * We are not responsible for any shipping-related issues after dispatch. No smokers or pets. Thank you. International buyers and proxy services are welcome. Size...M
