Clear like Scotch but thick like packing and durable ala duct tape, this clever prototype puts traditional door hardware along nonstandard edges and folds to create a cute optical illusion.

As a functional indicator of use, though, there is still a missing roll or two in this series – something like a sequence of illusory punched-hole or pre-drilled rivets or a set of steel plates would look more appropriate across seams meant to be cut and opened.

Still, as simple and clever go, this is a much more engaging variant of what are traditionally either boring or over-the-top elements of packaging and shipping, design wise, created by mmiinn.
