TierraCast buttons give you a combination of great style and versatility! This charming antique copper plated Skully button provides great macabre humor too! Each "stitched" skull button has an approximately 17mm diameter and includes a shank on the back with a 2.2mm inner diameter loop. Cast from Britannia pewter and plated antiqued copper, these Skully buttons are EU Nickel Directive Compliant and made in the USA. Use to make button-clasp closures on DIY bracelets, and as 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 TierrCast buttons on your favorite garments! TierraCast Safety Compliance Info.
