I bought a box of these (14 pieces) but I just want to open one or two and sell the rest.
I can't feel or see anything through the packs because there is a folded carton covering the thing inside. All I can do is measure them by weight and it doesn't vary by much. Still, there is a gap between the heaviest and lightest.

Assuming the weight per area are all uniform, can you sort all 22 variants by weight?
