EVERNEW Trail mat 180 t 9.0mm Thank you for viewing. I purchased this the year before last and used it three times for tent camping and mountain climbing. It's the same size as when I bought it. W500mm x L1800mm x T9mm As you can see in the photos, there are marks from the aluminum frame and scratches from use, as it was stored inside a backpack. Please make your judgment based on the overall photos, etc. There are no problems in particular with its use. The elasticity of the rubber band is also fine. Please consider this item with the understanding that it is a used product.
