Awkward, but still attractive and usable, packaging could be quite a lot of fun to design. Printer cartridge packaging is something that I’ve wondering about before. Everytime that I’ve purchased ink, the box always seems to be a maze of folds to get through, and I end up just tearing it apart to get inside. Im not sure about the USA, but in Australia there are quite a number of businesses that refill printer cartridges and give them back as is (it works out much much cheaper than buying them new, perhaps half). I remember once that I worked out it was cheaper for me to go and buy an entire new printer, than to replace the 4 cartridges that were empty with new ones.
On a side note, I’m in China at the moment, and the amount of packaging used/thrown away everywhere is on a crazy scale. It seems to be packets within packets, with literally everything having an individual wrapper.
