I have oxo pop top for flour and sugar, and use bought a set of ello containers on the Nordstrom rack site for about $30 and I love them for nuts and snacks, protein powder and stuff.

I keep my flours, sugar, brown sugar in glass jars on my counter. For other things I like the Oxo pop top containers — https://www.oxo.com/shop/kitchenware/pop-containers.html. They stay closed and are easy to open. One downside is that they hold less than I think because the lid sinks down into the container. But that airside they work well for me.

Do you have containers you love for flour, sugar, etc? I have some tupperwares I use and I love not keeping them in the original bags. But the I've had the same containers for probably 12 years, and have moved since then so the closet is different and I can probably find something more efficient. Any favorites?
