When storing things, whether it's in a garage or a basement or off-site, I recommend using clear water/critter-proof bins that stack easily.
I typically label them on a couple sides; you can do this with painters' tape and a sharpie, or you can tape pieces of printer paper on the inside of the box.
They actually make post-it notes that are sticky all over and those work great too, and can look a little more polished:
(There’s also post-it tape that comes in rolls of 1” or 2” that you can cut to size)
I default to these 66qt Sterilite bins, and I use these studier air-tight ones for special items or tougher conditions (like a dusty storage unit with heavy items and a fair amount of stacking).
I have come to really like the ones with the same footprint but half-deep for organizing things that I use more frequently and I use smaller sizes for office supplies and other things that are easier to keep separated.
I have a 30qt iris bin that I keep my snack staples in when I travel by car, and that’s been really convenient.
