The Osmiroid Mari 3 gold-plated stainless steel replacement nib unit is an all-in-one piece unit that includes the nib, feed and threaded collar. The Mari nibs units were designed to work with the Marion Richardson style of upright cursive handwriting taught in UK schools from the 50s to the 70s.
This is a New Old Stock nib unit that will fit into vintage Osmiroid and vintage Esterbrook fountain pens. The Osmiroid nib unit was made in England.
Please note: This nib unit will NOT work with the modern Esterbrook Estie MV nib adapter.
