I have a big suitcase in leather that I use when travelling to Sweden (so I can put lots of Swedish food for my Swedish colleague in it on the way back to Japan). I also have some smaller leather bags that I use for my magic props, and for shorter trips (and one of them I use as a set with the suitcase when travelling longer periods of time too, as a carry-on bag).
I have recently bought one more bag, even smaller. It is a camera bag, though I currently have a deck of cards in it. That is about all it can fit.
