We like how the lids have silicone seals and also are shaped so that the different sizes stack neatly and safely together. They also are straight and wide; no narrow necks or tops, which is a drawback to our otherwise beloved Mason jars. And of course glass is to be preferred over plastic.
These are a Japanese import, so they are not IKEA-style cheap, but sometimes it's worth paying for good quality, eh? Next time we reorganize the cabinet we may pick up a few of these.
