In-game Footage[]


  • Both the item itself and the description is a reflection of one of Isaac's nightmares between floors that involves him finding a razor blade inside a piece of candy.
  • The item and pickup quote are a reference to the urban legend of giving away candies with razor blades hidden inside of them as a way of harming people.
