I purchased this item new from SKT in January 2022, but I've only used it about 10 times. Each use was less than 30 minutes. I used it attached to a monitor arm I purchased separately, so I didn't use the included cover (and it has no creases). I applied a Miyavix anti-glare protective film immediately after receiving the new product. I will sell it with the film attached. As shown in the 20th photo, there is a thin line. I don't know when it appeared. You can see it when the backlight is on and the area is white. (Approximately 3mm vertically in one place, and approximately 10mm horizontally in one place) I took the photos under warm-colored lighting, so it may look discolored, but there is no change in the product's color. (It has been stored in the box for a long time.) I am selling it because I purchased a 25-inch e-ink LCD monitor and will no longer use this one. I have confirmed that it functions normally. All original accessories are included.
