Express your love for Planet Earth with TierraCast's sturdy, cast antiqued silver plated Earth buttons made of lead-free Britannia Pewter. Excellent detail on a round button with a shank. Perfect as button-clasp closures for bracelets and necklaces, and for embellishing leather cuff bracelets! You can also attach jump rings to the shank to make these earring focals 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 TierrCast buttons on your favorite garments! TierraCast Safety Compliance Info.
