A very simple cover to use a cosmetic tissue box available in the supermarket with a fancier look. The cover is bottomless and designed to put only the cover over the box.
I measured my tissue box beforehand and then scaled the cover in the slicer so that the tissue box fit tightly inside. This way it holds by itself. The cosmetic tissue boxes that are available in the stores in my region have a thin cardboard box and are easy to press into the cover.
