Purchased on Amazon in June 2025 and worn only once for casual wear. I accidentally bought the same item again recently, so I'm selling this one, which has only been worn once. (Actually, the other one I bought got a sauce stain at a yakiniku restaurant soon after, and the stain won't come out (crying), so it's now being used as pajamas.)

Shopping: This dry T-shirt, essential for active scenes, offers optimal comfort with its "4.1-ounce" thickness, excellent cost performance, and a wide range of colors and sizes. It's perfect not only as an inner layer but also for sports teams or groups to create original designs for matching T-shirts.
