I'll lower the price to 4000 yen. Dinos, So close Dark gray, 100% polyester, long-sleeved shirt, size M, button-up design. The fabric is thick, so it can also be used as a light jacket. The size is large (I usually wear L, but it's still quite roomy). - Color: Dark gray - Material: 100% polyester - Design: Long sleeves, longer in the back Thank you for viewing. Purchased about 2 years ago. I've never worn it and it's been stored in the closet. I would like to sell it to someone who will enjoy wearing it. It's new and unused, but it has been stored at home, so please refrain from purchasing if you are sensitive to this. I will fold it lightly and ship it. Thank you very much.
