This is a vintage lighter cover (or lighter holder) from Mexico. The bottom is marked Alpaca and the front of it has a black enamel background with a flower and two leaves inset of mother of pearl. It fits lighters very well and will continue to increase in value as less and less of them become available. This one is very pretty and is in excellent condition. It measures 2 3/4" long & has a 1/2" opening. This metal is referred to Alpaca Silver or Mexican Silver but is not a true silver piece.
