  4. Rated 5 out of 5


    I was sceptical at first, but after making my first different box size with the justfoldme cardboard sheets I found it very intuitive to make any box I wanted with just a few cuts and folds. I just followed their simple instructions. I really recommend to anyone who needs different box sizes and doesnt have the space to store old boxes. Will definitely buy again.
