What is the best storage for cartridges?

The humidor is a proper and cost effective device for the storage of multiple cartridges. Many can be found for under $25.00 US. Maintain 45% humidity. It is easy to use plastic dividers like they use for fishing lures and tackle. Hope this helps.

Humidor is the one and only choice.
Looks nice too and there is a wide selection of styles, decor and design.

K5
For me and my twenty odd cartridge/headshell collection, the rare and beautiful Fidelity Research K5 cartridge cases are the only way to go.
And if you're very very lucky.........you may even find the rarest K10 cartridge case? :^)

Dear all,
many thanks for these helpful hints! Humidor - yes. booked!
what about light? carts seem to like dark places, do you agree?

best & fun only

Natural lght (heat) just accelerates the drying out process.
