This 15x19mm distressed (hammered) oval button has two approximately 2.5mm holes for stringing or sewing. Cast from Britannia pewter and plated with an antiqued brass plated finish, these hammer-textured buttons are EU Nickel Compliant and made in the USA. Use to make button-clasp closures on DIY bracelets, or use as connectors and focals on earrings, necklaces, and more! 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 TierraCast buttons on your favorite garments!
