Had seen these cases at local sports stores and wanted to try them but the prices were prohibitive.  Found these on Amazon and the color I ordered (cypress green) appears to be a color they are discontinuing so they were a great buy. These make it easier to organize your suitcase and as I often travel with both business and casual clothing, I bought two different colors so it is easier to organize in the suitcase, and you have less worries in those instances where your bags are opened for inspection.

This case can easily hold up to eight shirts or blouses.

I would also highly recommend the 'tube' verion of these packing cases.  They are great for smaller items like underwear and socks, and fit well in the sides of suitcases around these larger packing cses.
