while you are rethinking your storage situation / strategy, i just want to give an endorsement for Cambro polycarbonate food grade containers. they make containers and lids that seal tight, last forever, and at volumes ranging from "i'm a normal kitchen human doing normal things" to "me and my several large adult sons will rule these wastelands with bellies full of grains and pulses" or maybe "this is for a commercial kitchen" i suppose. they are usually stackable and color options with transparent sides, usually with unit markings to tell you how much you've got left. stg, i do not have an affiliate link, lol.

if you're in North America, webstaurantstore.com usually has the widest selection, a powerful search tool and sometimes insanely cheap prices, but their costs for shipping are buttcheeks for residential addresses so it's a bit of a wash. i would make an account there regardless and request a free catalogue, because they are fun to look through. amazon can occasionally have some good deals on Cambro stuff, but their algorithm is shit and it will try to steer you towards knockoffs. sometimes i find the thing on webstaurantstore and then search for it on amazon using specific terminology. i like squared sides (as opposed to round) because i'm an efficiency asshole, but round bottoms have their uses if you want to occaisionally use smaller (~4-6 qt) containers for mixing ingredients.

not even Rat'xal, Lord of 10,000 Rats, could defy the sanctity of my grain and lentil storage situation. though there is a cat around here too, but the only thing he catches is naps.
