It is strange. I see such containers and a few rubles (completely thin type as single-use plates - or as for ice cream at 0.5kg which) and 30-40-50p in shops such as Ashan are already quite thick - but still another 10-30 times the maximum.
More or less decent really rubles 70-100, but this is either very large (0.7-1l) or still sets of 2-3 pieces. And the plastic there is already thick and higher quality.
Those that do not melt in the microwave and do not flow into the bag of the faithful are worth a hundred per piece, and yes, it must be large enough for the husband to eat. And +100 r for lunch every day? Yes, and it has to be a joke of some sort, so as not to wash out just one container.
