This box, designed in late 2020, is decorated with a shamrock, and folded from a single square of Tant paper. In contrast to most of my box designs, in which the lid is separate from the bottom part, this one is single-part and opens via a hinge. Two large flaps on both sides lock underneath a pleat that goes along the bottom of the box, making it possible to close the box quite neatly.

In order to limit the design to the convenient 16×16 grid, I ended up with a slit between the closed lid and the front wall. Using a slightly larger grid, it should be easy to add a small flap in front of the lid and ensure that in closed state, nothing can fall out of the box.
