Keys are powerful symbols representing the power to unlock (or lock) love, knowledge, special abilities, and more. Old-fashioned skeleton keys and winding keys are especially popular symbols since they evoke times past - plus, let's face it, they just look cool! Include these powerful symbols to your jewelry making with high-quality TierraCast key charms and padlock charms. These jewelry findings are made in the USA from lead-free Britannia pewter, then plated with your choice of several metal platings.
