I needed to mail a fairy door and wanted to find a small box that was quite sturdy. I remembered reading something about using a smooth-edge can opener to open a can that could be filled and resealed. So I grabbed a can of pears that had a tab top and opened it from the bottom. Once it was cleaned out, it was clearly the perfect size for the door which I placed inside with some packing material.
I sealed it using sturdy glue. Then I painted the top and spray paint and top-coated it with glittery nail polish. A computer-generated label finished it off nicely. Next time I will format the label so that the printing isn't as wide.
Now the recipient can use the pull tab-thingy to open it.
