the full size pigment jars are just the right height in those gladware containers - the sandwich sized ones. I was at the beach last week and in one sandwich size container I fit...
-5 fluidlines on their sides
-2 full size pigment jars
-2 sample size pigments
-1 e/s
-1 blushcreme
-2 mini paints
-trend eye pallete holiday 05
it was an exact fit, and I put the lid on with two rubberbands around it in each direction (4 total) and put it between two folded pairs of jeans in my suitcase. we drove, so there wasn't as much tossing around of my suitcase as there would have been if I was flying anywhere, but it was a good fit. i suppose if there was extra space you could stuff the container with cotton.
I also used one of the small round gladware containers to hold 2 mini paints and a pot of BE foundation, with maybe two cotton balls in between so it didn't shake around. popped on the lid, rubber banded it, and tossed it into my suitcase. worked great!
