I've been looking for airtight tupperware boxes with rubber seals for some time now, and the largest I have been able to get my hands on is 1 gallon. This works great for singles, but is just to small for boxes (
pictures). I have been looking for Rubbermaid online and on eBay, and it seems that I am able to get them shipped here but the shipping cost is almost $50...
But, I have found multiple shops that sells a type without a rubber seal. Will this work? The clips does shut the lid pretty tight, but I'm sure it's not 100% airtight. These are both cheap and easy to get, but can I use them as tupperdors?
I think coolers are easier to get, but I really like the ability to stack the plastic boxes.
