On several occasions, I go to the Migros to buy a colander. And I end up having to buy three (but what to do with them: the last one lasted me 19 years). So I came home empty-handed. The product offered doesn't correspond to what I need :(.

For people who need a lot of colanders, it's a good idea to offer them in sets of three... But I'd find it very useful to be able to buy them by the piece too. It would be so cool if you could make the adjustment!
