Approximately 16mm TierraCast® antique gold plated round triskele buttons. The triskele is an ancient Celtic symbol featuring three spirals. It is used all over the world. These buttons are part of the TierraCast Celtic launch. Great for making button-clasp closures for bracelets and necklaces, or for embellishing our leather cuff bracelets! TierraCast completed rigorous testing to determine how well these buttons hold up in the laundry and dry cleaning process. We are thrilled to report that all finished hold up beautifully through the washer and dryer cycles. Chemically antiqued finishes are also fine with dry cleaning, but the -AS Antique Silver Plating and -AG Antique Gold Plating should not be dry cleaned. So go for it. Try TierrCast buttons on your favorite garments! TierraCast Safety Compliance Info.
