Pen Filler - while the Snorkel can be used to fill only converter-cartridge pens, the pen filler can fill any pen on the market – lever pens, piston pens, plunger pens, converter pens and even the old eyedroppers – with a small amount of ink.
Instructions - the pen filler comprises a transparent reservoir, a broadly knurled pen-locking section and a finely knurled top for closing the inkwell.
