You may find that you need several sets of these all purpose containers. I keep them in the cabinet so that I don’t get light on the ingredients. The air tight seals allow for foods to stay fresh for a long time and it keeps critters out. These come in a variety of sizes and you’ll find that you’ll wonder how you ever lived without them. I use markers to note the contents, as with so many different types of things like powders and flours, you can easily get them mixed up.
