Slim CompactFlash card holder

Very slim and quite rigid holder for 3 x CompactFlash (CF) cards.

It has two cut-outs on each side for each slot, so this way you can manage which cards are used and which cards are not. There is also parallel markings on the front side, to tell which cards is #1, 2 or 3.

You can also add a keychain ring or a paracord to it.
