I know there are many other bins for sanding papers. However, I couldn't find one that is customizable. Compared to most others, this one does not require supports, perfectly stackable and fully customizable, including size (5'', 6'' or any value), height (24mm is default), thickness (3mm is default), grit text on the side, rotation, size and font type. Just touch the text with permanent marker to make it stand out.
