I often reuse cardboard boxes to temporarily store items in them, but the outer cover flaps keep opening, and I don't want to seal them with a tape or put something on them.
So I designed this clip that keeps the flaps shut and at the same time allows me to open the box easily.
There are two parts and they can be glued to a surface of a box with a 2cm wide, 1mm thick double sided foam tape.
If the clipping action is too hard or too weak, you can adjust the horizontal size of the top clip by a few tenths of a millimetre in your slicer.
