The great thing about Tupperware is that it comes in so many different sizes, lengths, etc. to where one can tailor as to storage ideas. That one pictured is great for stacking....and as far as ensuring sealability using a seal ensures there is no leakage. I tend to use RubberMaid products where I "burp" the top and know there is no issue with any leaks and they can be found at most discount places...Dollar Store, 99 Cent Stores, Big Lots, etc. and I found a bunch of them that had the 2.5 gallon size for like $5. This size holds about 175 Robustos....200 Lanceros.....125 Toros. For the money it is a great investment and your cigars are guaranteed fresh when stored in a closet setting...no lights, dark area and I use KL as my media and it holds at a perfect 65/70.
