Be strong and face danger with this bold design. Skulls have symbolized death for thousands of years but they have also been worshipped for the strength and protection they afford. In Mexico every year, skulls are the memento of the Day of the Dead (Dia de los Muertos), a celebration of the memories of those we love who have passed on. Made in California by TierraCast® of metal both lead and nickel-free. They are considered hypo-allergenic. This is a great button for almost any project with its shank generous enough to fit up to 2.0mm leather.
