The material is titanium for the post, brass for the ball, and stainless steel for the rest. It is a catch type. You can pass parts through the hoop or connect the parts you made. After passing the parts through, use adhesive to glue the round ball at the tip. *Due to the manufacturing process, the shaft may turn blue, but this will not cause any problem when using it. *Titanium is a metal that is unlikely to cause allergies, but in rare cases, some people may develop metal allergies even with titanium. Please be careful when using.
