1, the main body is made of pure copper, test with a suction stone, please avoid the spring part. Springs and screws are iron, the purpose is to increase the strength!

2, the surface nickel-plated treatment, so not brass color. Because copper is easy to produce copper green in the air, nickel is not active, can prevent copper green, increase the luster, and more wear-resistant
