I grew up with Tupperware, have also had some "cute" ceramics, some slant-face clear glass ones that look like the one choclatechef pictured .... but now I've settled on commercial square clear polycarbonate food storage containers made by Cambro (1st choice) or Carlisle (2nd choice - appers to be identical to Cambro) or RubberMaid (3rd choice - I don't like their handles and they seem thinner and not as sturdy as Cambro or Carlisle).
I prefer square because they hold 30% more than a round canisters of the same width and height.
