Those pre-made containers are great. I was redoing my humidors recently with all the new additions and decided to dump all the bowls of beads and order the 65% bead containers from heartfelt. They fit where the foam humidifiers would have gone so no space is taken up by humidification anymore. Worth every penny.
I forgot to order a small 60 percent tube for my 20ct so I ordered that last week plus a bunch of accessories. I like to keep a small selection of cigars on the main floor so I don't always have to go to the den in the basement to get a stogie.
