Collar inspired by the one Batman wore in Batman: Noel and Batman: Damned comicbooks. It was designed to work with Mezco One:12 bodies, but with some scaling, it should fit other brands as well(VTOYS Zero body, for example). The collar goes over the neck of a One:12 Batman figure with no issues, it's meant for muscular bodies. The gap between the back of the figure and the collar is so that the cape won't get damaged when putting the collar on. Necks the collar can go over:
The pictures with printed collar on a figure are with V1 of the collar, I replaced the files and previews to V2 with more defined Bat emblem.
