Deck out your keyboard with the busts of everyone’s favorite ninjutsu-knowing, pizza-eating, New York City sewer-dwelling turtles. The set of four keycaps comes in your choice of four different series: Classic, Clear Colored, Clear Green, or Zombie. The Classic and Zombie keycaps are designed to allow backlighting to shine through the turtles’ eyes, while the Clear versions allow backlighting to illuminate the entire keycap.
