Sailor 1911 L Demonstrator ST Fountain Pen
The Sailor 1911 L Demonstrator ST Fountain Pen pairs a fully transparent body with a rhodium-plated 21K gold nib and silver-coloured trim. Its clear construction reveals the converter, feed and ink inside the pen while retaining the balanced, rounded profile of the 1911 Large. It is an excellent choice for ink enthusiasts, collectors and writers seeking a premium Japanese fountain pen for regular use.
Choosing your Sailor nib
Nib width influences line size, writing feel and the way an ink appears on paper. Visit our guide to Sailor nibs to compare the available options. For advice about the nib sizes currently offered with this model, contact us at inktraveler@inktraveler.com.
Transparent demonstrator design
The clear PMMA resin body turns the internal structure of the fountain pen into part of its appearance. The feed, filling mechanism and chosen ink colour remain visible through the barrel and cap. Sailor complements this transparency with a silver-finished clip, cap bands and metal accents, creating the restrained ST or Silver Trim configuration.
Its rounded, cigar-shaped profile follows the traditional design of the 1911 collection. The Large format provides a substantial yet balanced grip that suits medium and larger hands particularly well. The threaded cap keeps the nib protected and can be posted on the back of the barrel when a longer writing instrument or a different balance is preferred.
Rhodium-plated 21K gold nib
A 21K gold nib with rhodium plating provides the controlled response associated with Sailor writing instruments. It produces a precise line with steady ink delivery and a distinctive tactile connection to the paper. This is not intended as a flexible nib and does not require pressure; its performance comes from careful tuning, consistent contact and natural movement across the page.
The selected nib width can be matched to handwriting size and purpose. Finer points support small lettering and detailed notes, while broader options display more shading and colour variation. The exact nib grades available for purchase are shown among the combinations on this product page.
Cartridge and converter filling system
The Sailor 1911 L Demonstrator ST accepts Sailor’s proprietary ink cartridges and converter. A cartridge provides a quick, convenient refill when travelling, while the reusable converter opens the door to bottled inks and makes full use of the transparent barrel. Explore our selection of fountain pen ink bottles and cartridges to choose a suitable colour.
The clear body makes the remaining ink level easy to check. Highly saturated colours may leave a slight tint on transparent components after cleaning, but this does not affect normal operation. Flushing the pen with room-temperature water between colours helps maintain its appearance and prevents different inks from mixing inside the feed.

ST and GT finishes
ST denotes the Silver Trim version, fitted with a rhodium-plated nib and silver-coloured metal details. The GT alternative uses gold-coloured trim. Both versions share the clear PMMA construction, 1911 Large proportions and cartridge-converter filling system, allowing the choice to be based primarily on the preferred metal finish.
Sailor history and craftsmanship
Sailor began in Japan in 1911, when Mr Sakata and his brother established a workshop to manufacture solid-gold nibs. The company developed the world’s first 21K gold-nib fountain pen in 1969. In 1981 it introduced the original 1911/Profit design, combining seven decades of accumulated knowledge with a well-balanced body shaped for comfortable writing.
The Demonstrator applies that heritage to an open, contemporary design. Its transparent construction shows how the ink, converter and feed work together, while the familiar 1911 silhouette preserves the traditional feel of the collection. The result is a pen, writing instrument and collector’s piece whose appearance changes with every ink colour placed inside it.
“A fountain pen that makes every chosen ink colour part of its design.”
