A security wallet or container for carrying credit cards is in the form of a rectangular hollow body containing a drawer to hold a stack of the cards. A combination lock is operative to block movement of a release pushbutton depression of which causes the drawer to spring open, when pushed back into the body the drawer automatically latching in the closed position. A defacing mechanism operates to discharge a dye or other defacing substance on to the contained cards in the event of forcible opening of the wallet or container without unlocking of the combination lock and depression of the pushbutton. The defacing substance is contained in a pressurized capsule mounted in a carrier which is spring loaded towards a blade mounted at the inner end of the drawer, the carrier normally being held back against the loading springs by latch means which are freed in the event of the drawer being forced open or a tensioned cord severed or released if the body is cut open.
