TierraCast buttons give you a combination of great style and versatility. This antique gold plated 12.5mm Czech-style round button lets you add a special touch to your handmade jewelry designs. Each detailed, cast button is cast from Britannia pewter. The Czech round button design is based off antique glass buttons from the Czech republic. These buttons are EU Nickel Directive Compliant and made in the USA. Use to make button-clasp closures on DIY bracelets, and to add focal decoration 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!
