The Onoto Magna Plunger-filler, Henry Simpole pen

A masterpiece of design and craftsmanship

For years, the 1937 Onoto Magna has been the prized possession of many pen collectors. Renowned for its style and balance and of course, for its plunger-filling system, the Onoto Magna had no equals – until now! Today, the recently introduced Magna Plunger-filler range brings together all the style and iconic design elements of its predecessor as well as the remarkable plunger-filling mechanism.

And now, here’s an exclusive silver overlay edition by the world famous overlay craftsman, Henry Simpole.  

Henry’s delicate silver filigree work is the stunning focus of this edition of the Magna Plunger-filler. Hand-crafted in his London studios in sterling silver, each overlay is fully hallmarked and includes the words ‘Onoto The Pen’ cleverly but subtly interwoven through the vines and leaves that make up the design. 

A superb pedigree

Stylish, elegant and tactile, this new edition of the Magna Plunger-filler has a superb pedigree and follows a proud Onoto tradition of Art Nouveau silver pen overlays dating back to the 1910s. Yet it was the astonishing plunger-filling mechanism first devised by George Sweetser and Evelyn De La Rue in 1905 that helped put Onoto at the forefront of pen manufacture in the 20th century.

The plunger-filler was eventually withdrawn in the 1950s partly because of the cost of manufacturing such an intricate mechanism and partly because of the fashion for more streamlined pens. However, it remained a firm favourite with Onoto enthusiasts and collectors around the world, and now, following many requests, the creation of a new Onoto Magna with a true plunger-filling mechanism has become a reality.

Virtually maintenance-free

The Onoto Magna Plunger-filler has an impeccable lineage and has been developed using original Onoto drawings: the same classic design; the same chevron clip; the same plunger-filler vacuum system. However, key components are now made from better materials than those which existed 60 years ago. For example, the plunger rod is made of carbon fibre; the cup valves are a special silicone rubber and there's an ingenious 3 washer seal that we believe gives a much longer life than the original cork seals. This makes the brand new Onoto Magna range virtually maintenance free.

Huge ink capacity

What’s more, the ink capacity is 3 mls, more than 4 times the capacity of a standard K5 converter or cartridge, so you have much longer writing time than most modern fountain pens.

Cut off valve prevents leaking

And, just like the original plunger-filler, The Magna Plunger-filler also features a cut-off valve which seals the ink reservoir when the pen isn't in use. Simply turn the valve by half a turn and it's ready to write!

18ct gold size 7 nib

As well as being beautiful, this new Onoto overlay is a wonderful writing instrument with the famous 18ct gold size 7 Onoto nib –available in Fine, Medium or Broad.
