You can practically HEAR this button!  Black bat on green backsplash on translucent yellow button, but fully customizable to your choice of colors.  Splash points have nice surface curvature so they’re not sharp and stabby.  Batman-esque font and eyes in negative space so the base color light shines through!   Also available with housing/switch assembly ($5 extra) to fully replace small recessed button on the early run machines.
