I have attached 2 cones back to back with a bit of rod or w/e in the middle. They are very similar to the the cold steel ones and they work well. you can shoot multiple darts, marbles, Bbs or just about anything that will fit in the blowgun. marbles work well but if you shoot a hard target they will break into sharp chunks of glass that you may or may not find. I have used 1 inch pom poms as "cones" on darts but have not tried using them as wads yet.
