MUJI Flannel Shirt, Long Sleeve - Price Reduced Although it doesn't have a tag, it's a new, unused item. The fabric is thick due to the brushed finish, making it perfect for the coming season! The color is also basic and the design is timeless, so you can wear it for a long time. Size 80 MUJI shirts are durable, so please wear them often. It's one of my favorites, but I'm selling it to declutter.
