Box for papers

I had blood tests on Tuesday and will get the results in a couple of days and the statement by the oncologist next Monday. They will hopefully show that the medicine given as injections is working, and that I will still have time to organize some papers and some items that I do not want to be thrown away.
These boxes have been dimensioned to take the standard A4 size papers, but they are also neat for all small items and books. I ordered 20 pieces from Ikea and managed to fold one box.
