The ''coin filler'' is a variant of the previous ''match-stick filler'' system in which instead of a match the user pushes directly on the pressure bar using a coin or a medal or similar object, often elliptical in shape to allow a smaller width of the slot made on the pen body. Also in this case, in fact, the pressure is exerted through a lateral opening made on the barrel of the pen.
