That design looks more difficult to work with than the half-gallon and quart containers that we get in most of the United States (those are waxy cardboard rectangles with square bases and peaked tops), but a lot of people have used them for molds to make block-y things, whether literal blocks, candles, or something else. The waxy coating on the inside made everything easy to remove.

Those, though? As long as there’s no smell left, I might suggest just using them for storage. They look well-made for anything from oil to beans, since they’re not going to let air or light in.
