This is the Axesquin Elements Solotex Short Collar Shirt. Made of 70% polyester and 30% wool. The color is "suminezu" (a grayish-brown), and the size is 4, which I believe is equivalent to a size L. I'm selling this because I have too many shirts and I'm decluttering. It's a clean used item, with no noticeable stains. I hope someone who understands used items will appreciate it.
