Etched Glow-Through Keycap - Zener ESP Square Design

When we saw the classic "Zener ESP Card" designed keyboard in the awesome CHVRCHES video for the song "How Not To Drown" (ft Robert Smith!) we were smitten. So goth! So esoteric! So we got a small number of these etched-through keycaps with the 5 designs: circle, cross, waves, square, and star. You don't have to wear excessive eyeliner to snap these into your mechanical keyboard... but, hey, we'll use any excuse.
