Get a big cooler, buy a pound of beads I prefer 65%. Clean cooler and absorb smell with baking soda. line with spanish cedar slats from cigar boxes. place distilled water in an open container on the bottom place 1/2 lb of beads in another container. Allow beads to absorb moisture. Remove distilled water source. Place boxes in cooler close lid check periodically for bead condition per manufacterer.

For singles I prefer real humidors. I like to lay some churchills evenly spaced and without cello perpendicular to the direction I will lay the other sizes. Put down a layer of cigars with no cellophane. Then another set of churchills. etc. allows air flow .

Turn the cigars periodically to prevent damage and flat spots.

Don't smoke them for x amount of time. With boxes smoke one every six months or so and keep a journal about development from aging.

I'm a newbie with a lot of potential and posts. Just started aging boxes. AVO Maduro robusto, Private Stock Maduro robusto , Torano Exodus 1959 Perfecto.
ISOM's are illegal so I have none.
Lots of singles in two box humidors, boxes in a footlocker humidor. Life is good.
