I'd just like to add to what Horseshoe posted up above. For a small number of sticks a tupperware container with Boveda packs is pretty much perfect. You don't have to worry about seasoning and it is a very cheap investment. The Boveda packs will eventually dry out (they get hard and no longer gel-like when they are done) but they can be rehydrated! Stick them in either a ziplock bag or another tupperware container with a damp sponge until they feel like gel again and you'll have brand new packs. This can save you money in the long run. Maybe keep a couple sets and have one rehydrating while the other humidifies and swap 'em out every so often.

Now for larger storage I recommend a cooler and it's what I currently use. You can use Boveda packs here too but it can get a bit expensive because you'll need a lot of them. A better option for a cooler is to use a bulk humidification medium that you'll occasionally have to spritz with distilled water. The more expensive version of that is Heartfelt Beads but I've heard very good things about them. The cheap-ass version (my choice) is to use kitty litter. It has to be unscented and it has to be the clear silicone crystal kind. Exquisicat Crystals are a good brand for this. The kitty litter works just like the beads, put it in a container with some holes and occasionally spritz it with water to maintain humidity.

For the cooler with HF or KL you'll need a hygrometer. There will bit a little bit of work figuring out how much to spritz your humidification medium to get the desired humidification level (65% is a good start) but with a bit of trial and error it's not too bad.
