Each detailed 16mm antique silver plated "Bamboo" metal button features stylish bamboo leaves and stalks on the front and a 2.2mm inner diameter loop (shank) on the back. Cast from Britannia pewter then plated with an antiqued silver finish, these bamboo buttons are EU Nickel Compliant and made in the USA. Use to make beautiful 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 TierrCast buttons on your favorite garments! TierraCast Safety Compliance Info.
