I have one without a handle and it keeps a cake beautifully!
However, for the past 3-4 years, I've turned it upside down and used it to mix and hold my bran flakes and multigrain Cheerios. It holds two boxes of cereal perfectly and keeps it fresh!
I, also, have one like the one that you have now. But that one does NOT have the locking lid, and you just gave me a very brilliant idea. I'll do that with my old one!!
The wife or the old neighbor have one similar to that. I just lift the top when it is on the counter to see what goodies it may contain. They send a lot of stuff back and forth in it. Pies fit in there nice also.
