Please also read my profile. "Uniqlo and Muji Long-Sleeve T-Shirts Set of 2 Long Sleeve T-shirts, Size L and XL" I wore these for one season, but I no longer need them, so I'm selling them. There are no yellowing or stains, and the condition is good. I think they can be used as innerwear for sweatshirts, shirts, sweaters, suits, etc. They might be good for middle school students as well. ● Colors Uniqlo: Navy, Muji: Black (※※The Uniqlo one is navy, although it's difficult to see in the photo) ● Uniqlo (Navy): Size L (cm) Shoulder width 36, Sleeve length 57, Body width 40 Hem width 42, Length 59 ● Muji (Black): Size XL (cm) Shoulder width 40, Sleeve length 61, Body width 46 Hem width 48, Length 62 (Please note that these are amateur measurements taken flat, so there may be some slight errors.) ※Please excuse any folding wrinkles.
