18x15mm Bright Gold 4 Ring Intermix Link by TierraCast. Intermix is a collection which taps into the current culture mood - a desire of sometimes wanting to escape to another planet. These interactive links were developed from a tray of textured sheet metal. The texture pattern and organic round shapes of the links are reminiscent of the surface of the moon. The true magic happens when you begin to Intermix these links to create your designs. The options are as endless as the two trillion galaxies which make up the universe. These lead-free pewter links are made with high quality metals. Made right here in the USA!
