If you knew how much space and energy we waste when shipping stuff in square boxes, you’d start delivering stuff in person. So what you need is this special box that wraps around your object perfectly.
Sure, it looks like a body bag from the photo, but the Universal Packaging System, or UPS, is a design by Patrick Sung that wraps around your object, thanks to being divided into small triangles which give it flexibility.
On second thought, the uneven shape is probably less efficient to stack and in the end, it might end up wasting even more energy. The packing would be more time consuming as well. Still cool to see it and should work very well for very odd-shaped objects.
