@William191 This is what I have used for years and am very satisfied, $1.50 at the Dollar Store.
I change them out every 6 months. Cheap and work great. 
P.S. Made in U.S.A.

I use damp rid containers from years ago & fill them with 100% calcium chloride ( normal use for snow & ice removal, 20# bag lasts a long time) & before some folks talk about rust, it does not.

I too have a wooden ammo cabinet. I use something just like what @BRUCE26 uses. It works really well. I have a lot of it in ammo cans too with the little desiccant packs inside. Between the two, the ammo looks just great after a year.
It is inside the climate controlled part of the house though.

Haha, the ammo for my 41mag is pretty old and has ever only been kept in a similar cabinet or just in a paper bag on top shelf in a closet. I mean around 20 years old or longer. Will have to go shoot some this summer.

I have a 12x12 room in the basement, cool-dark-dry is the key. I run a large dehumidifier in the room for 4 hours once a month. For really long-term storage I vacuum-seal everything.

Also a side note, I use silica gel (normally used for drying flowers) in any porous fabric or coffee filters for ammo stored in cans.
