This is a 4" avengers "A" on magnetic (or 3M adhesive if you prefer)
It is a multi part build, with different components heights for a "3d ish/raised lettering look" with a 1.5mm "A" and and 0.5mm inset black insert with texture. The black has a texture that looks similar to the texture of the rails/hinge or coin door.

(looks great on the right side flipper protector too, but due to the alignment will not fit on the left side :(

Looks perfect for the coin door or hinges. (at 4" tall it's exactly the size of the hinges height)

by default I'll put them on magnetic material unless you choose the 3M adhesive option.
