Based on the style and shape of one of the most famous fountain pens ever made – the Onoto Magna of 1937 which is still acclaimed by many as the best fountain pen ever made – this Magna Plunger-Filler has a sterling silver cap band bearing the signature of the Plunger-Filler mechanism designer, Roger Wolfe, with the sterling silver TDLR clip.

Hold the Magna Plunger-Filler and you will marvel at its perfect balance and how tactile it feels – it is also one of the most robust pens on the market today, thanks to its durable, high density acrylic composition.

The distinctive Onoto logo is carved into the sterling silver cap button with a frosted background, making it instantly recognisable, and a sterling silver barrel button finishes the overall luxury feel.

The Plunger-Filler comes with a No. 7 18ct Gold Nib as standard and is available in a limited edition of 200.
