Only tried on, never used ꕤ︎︎·͜· Purchased from a shop in the Gangnam underground mall. The material is not itchy. After purchase, I was concerned about the smell, so I hand-washed it once. There is no inner tag, and the material is unknown, but I think it's synthetic fiber. There are no noticeable stains or fraying. Please understand that this is a new/unused item before purchasing. Please refrain from purchasing if you are sensitive to such things. ● Other notes: Stored at home. Please check the details of the design in the photos. Color: Khaki系 (khaki-like) Neck: Crew neck/U-neck Stains/tears/smell: None
