The bulbs rotted in the jar

What the constraint row says
All four leaves in this group report the same process note: moisture is the enemy, sealed closure plus a desiccant. That is a blanket default, and it is correct for dry dormant seed and wrong for the rest.
Bulbs are respiring
A bulb is a living storage organ, not a dormant embryo in a dry coat. Sealed with a desiccant it either suffocates and rots or dries out, and both failures are slow enough to look like bad stock rather than bad packaging.
What a bulb actually wants
Air movement and a stable cool temperature. Mesh, paper or an open tray answers that. Nothing on this shelf is vented, so this is a case where the honest answer is that we do not have the container.
Cuttings want the opposite of a desiccant
A cutting has to stay turgid until it roots. Moisture is the thing to keep, not exclude, so a desiccant is precisely the wrong component and a sealed humid environment is closer to right.
Seed starting is not storage at all
It is a growing container, and it needs drainage. Nothing on this shelf has a drainage hole, which disqualifies the whole shelf for that leaf however good the jars are.
Why say all this rather than drop them
Because somebody searching for a bulb storage container should land on a page that tells them what they need, even when the answer is that we do not stock it. The alternative is selling them a jar that kills the bulbs.
Seed is the leaf this shelf serves
Dry, dormant, and the one the Federal Seed Act reaches. For that, a sealed jar with a good liner is genuinely the right container and the regulation will even extend your test window for it.
