Packaging should have standard sizes, e.g. 500g, 1kg, 2kg, 4kg, 8kg, 6 units, 12 units, 24 units...
Sizes of 230g, 450g, 1.3kg are a dark pattern that makes nearly impossible for consumers to know what they are really buying and how much they are paying for it. A really honest company would never do that kind of nonsense.
