Some remarks: | |||
* not all 4 elements are always specified, eg 250 g means 1*250 g for the entire product | * not all 4 elements are always specified, eg 250 g means 1*250 g for the entire product | ||
* sometimes more than one quantity is specified, e.g. 250 g (5x50 g) might mean 1x250g for the entire product OR 5 50g pots | * sometimes more than one quantity is specified, e.g. 250 g (5x50 g) might mean 1x250g for the entire product OR 5 50g pots | ||
