Purchased these for my boyfriend, and he absolutely loves them! Not too heavy, and are true to size. I did some price matching prior to purchasing them, much better price than anything you'd find anywhere else.

Great to have some steel plugs of one of my favorite comic book characters. They go right in & catch everyone's eyes. Screw fits are one of the best styles for plugs & tunnels since they are the most secure no matter the situation.
