I've been hunting mouse proof storage for my Christmas decorations and ornaments. This year I purchase several pieces of used hard-sided luggage at the local thrift store for a very low price. Sorry mice friends!
I would think plastic storage containors would have been just as thrifty plus you could store more in them. You can buy a fairly decent sized one @ walmart, Kmart or Target for around 10-15 dollars.
But I guess if it works for you, that is all that matters. I personally store jigsaw puzzles in my suitcases however I did not purposely go out & buy the cases to do this. I just figured puzzles were not something I work with everyday and they were taking up room on closet shelves so i stuck them in suitcases.
