Thank you for viewing. This is the famous Vitra Tool Box. The color is gray, but due to the recycled plastic material, there are dots and areas that appear to be colored, which is characteristic of the material. This is not dirt acquired after purchase. Please check the photos. I have been using it for about six months. There is some minor wear and tear, but it's not very noticeable due to the nature of the recycled plastic material. Please consider this item with the understanding that it is used. Thank you.
