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.

I had been looking for something like this as I send a fair amount of parcels that are all different sizes. It is a bit more expensive and takes a bit more time than i would have liked, but it does the job and time required improves with experience.


If you never have the right size of cardboard box to post something in, try these. It just needs a bit of planning, and you can make just what you need. After you’ve made the first one you’ll get the hang of it, though there are instructions included. I’ve posted breakable items in a box I made from this kit with no problem.
