Waterproof Memory Card Case Holder Anti-Shock Camera Card Box Storage Protector for Micro SD/TF/SD/XD/CF/XQD Cards 27 Slots with Carabiner.(Black)

Very nice sturdy case. The fit of the sd cards is very tight, but that means they will stay in place and will not be bumped loose. I haven't tested the waterproof capabilities and probably won't do so intentionally. I like the case a lot, hopefully will save me from losing the spare cards for my camera.

Only holds 2 C-Fast cards. Not worth the size for just 2 cards..

Tough construction.

If you want to damage the SD card then buy such houses :(
