I store more seeds than most (Market Gardner).

Large seed (think, like, pea, corn, bean and the like) get stored in quart and half-gallon mason jars. Use the actual canning lids as these are air/water tight. The white plastic screw-on convenience lids allow moisture to seep in.

Small to mid sized get stored in dirt-cheap prescription pill bottles - either 8 dram or 16 dram size. You can get more than you'll ever need for, like, $30 bucks. I think mine were 250 or 270 bottles for $30 bucks. Go in with a few friends. You'll never use 'em all. These aren't water tight. They go inside a Rubermaid container with a gasket that keeps moisture out.

The Mason Jars sit in a dark basement that stays near 60(f) year round. This is key to longevity: Consistent temps. Wild fluctuating temps are a no-no.

The pill bottles inside their Rubermaid get stored in a dedicated freezer kept at 10(f). Seed stored here pretty much last forever. Like, when they tell you Onion seed will only last 2 or 3 years? I've seeded 10 year old Onion with better than 80% germination (was inspected at 92% by the seed company, so it didn't really lose all that much in a decade. )

This works for me.

250-ish varieties across 70 or so distinct crops.
