JJC Multi Memory Card Case MC-SD8 memory card protection box for 8 SDHC Cards - Extreme Waterproof and Shockproof Bag Case Box Safe storage envelope (Personal Computers)
The case is really well made, but you get the memory card down badly in the rubber frame, they drop out repeatedly during opening. The part I have in use and if I watch, nothing falls out. But cards should keep better.
