Approximately 12-gauge pink anodized aluminum craft wire (jewelry wire), 39ft (12 meter) package. This wire is 2mm diameter and very lightweight! Made of alloy number 1060. Because the colors are not plated, they are more durable than plated colors. Great for weaving and wrapping, and for practicing new techniques. Aluminum wire is soft and scratches very easily. Use nylon-jaw pliers or Tool Magic™ to prevent the color from scraping off.
