If you love skulls, you’re going to love this button by Tierracast. For centuries skulls have scared us, protected us, and even transported us to the afterlife. Add one in your next design and it can symbolize courage and strength. 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.
