With a lack of “official” merchandise, many fans have taken it on themselves to recreate various props from the series. While most of the times these center around the infamous PPG pistol, or various quality replicas of hand-links, occasionally you can find other replicas as well.

The original prop had areas carved out of it to make it more 3-D, but it is difficult to tell if this one was made as precise or not. Still, a fun piece to have sitting with your collection to be sure!
