Come to think about it, the two huge plastic containers with lids that I keep the cat food in are both old, old Tupperware containers. Stained on both of them, but still air tight. Each holds about the size of a 10 pound or more sack of sugar. Don't really remember how old, but at least 30 years. Like I said before, it pays to get the best you can afford, so you won't have to be constantly replacing it.
