The Media Keeper is a felt-lined pouch made from top-grade leather that opens like a wallet. It features two pockets that nicely fit a CF card or an SD card in a jewel case. The hook fastener secures the contents and offers quick, easy access. The Media Keeper can also be threaded through the quick disconnect (QD) on Op/Tech camera strap as an added safeguard.
