bout the Nanga:
If you are familiar with my pens, then you probably know I derive the names I use from Wikipedia's "list of the worlds tallest mountain peaks". This pen follows in that same tradition by being named after the Nanga Parbat mountain peak. The name "Nanga Parbat" means "Naked Mountain" with Nanga specifically meaning "naked". Since this pen appears to be absent or "naked" of any barrel threads, I thought Nanga would be a very appropriate name for the style. If you wish to read more about the Nanga Parbat mountain peak or about any of the other pen names, you can read them on my Pen Names Page.

Nanga Dimensions:
The Nanga is now available is several size versions: Standard, MAGNUM, and Midi. The Standard size Nanga has a capped length of about 6" (152.5mm) and uncapped length of about 5 1/4" (133.5mm). The max diameters are barrel .61" (15.5mm) and cap .64" (16.25mm). The MAGNUM size Nanga has a capped length of about 6 1/2" (165mm) and uncapped length of about 5 1/4" (146mm). The max diameters are barrel .69" (17.5mm) and cap .73" (19mm)*. The Midi size Nanga has a capped length of about 5" (127mm) and uncapped length of about 3 11/16" (94mm). The max diameters are barrel .535" (13.5mm) and cap .55" (14mm).

*MAGNUM Cap diameter... The standard size for US made pen blanks is .75". But some European blanks are sized smaller at only 18mm (.71"), so the cap may have to be thinner based on the diameter of the material you choose. The .73" target diameter is based off the enlargement percentage of the standard size Nanga, but the difference is minimal and would not affect the overall look of the pen (some of the pens shown are under .73").

The unique forward mounted threads on the Nanga allow it to have a nice free flowing style. The smooth transition across the front-section and barrel allows it to have a smooth and graceful flow along the entire length of the barrel. As the different size versions show, the design also allows some flexibility in the diameters so it could be adjusted to fit small or large hands. As with most other JEB's PENs, the Nanga can be ordered in any of the materials shown or your material of choice. The pen includes a steel Meister nib in your choice of finish and tip size. The standard inking system is Cartridge/Converter, but if you like to use your pens as eyedroppers, you can order the Nanga with a special rubber o-ring that seals the section to the barrel so it can be filled directly with ink (not available for the Midi). The larger #6 nib is the best size for the Standard and MAGNUM, while the smaller #5 is required for the Midi. Nib finishes available for STEEL nibs are: 2-tone, polished steel, Black Oxide (#6 only), or Ruthenium (#5 only). Current tip sizes are x-fine, fine, medium, broad, and two italics (1.1 both; 1.4 for #5 only, and 1.5 for #6 only). 14 & 18K Gold nibs are also available as a special order.

Nanga Options and Upgrades:
The Nanga is another pen style that allows for a few upgrades and options. You could add metal accent bands to the base of the cap, or add a slot-mounted clip with a hidden ring (see the main page for a few pens made with this type of clip). The accent bands are available in several finishes (24k gold, nickel and Rhodium, and come in a variety of diameters with widths from 1 to 4mm (1mm increments). As stated above, you can also upgrade your pen with a 14k or 18k gold nib. For the fans of the Nanga MAGNUM, I also have a souce for the larger #8 nibs. However they are only available in the BOCK style nibs in 18k Gold or Titanium Semi-Flex. Contact me if you are interested.

Inking system upgrades... NEW October 2021: The Nanga is now available as a button-filler! The button-filler barrel is 1/4" longer than the standard barrel with a 3/4" long blind-cap. So now there are FOUR inking system options available: 1) the standard C/C; 2) Eyedropper with a custom fitted o-ring; or 3) Bulb-filler; 4) the new Button-filler.

Miscellaneous items... I also offer a variety of other items: a) hand-made Props and Buttons for pens as well as Cuff-links in a variety of styles. You can order a Pen Prop in a material to match your pen, or any one of the wooden styles made in a variety of stained or dyed colors. The Pen Buttons are available for any of the clipless pens. The Cuff-links are available in a variety of styles and finishes and can be ordered with your choice of insets.

About this Pen:

This is a standard size clipless Nanga. But what makes it different is the Vacumatic style inking system used (see additional information below). And because of the special inking system, the barrel is made in one piece (excluding the blind-cap). Normally the Nanga would have a separate 1" long Section at the front that unscrews for refilling. But since it's not necessary, the main part of the barrel is all one piece. The Blind-cap is about 1 3/16" long to hide the Vac's plunger, but is basically invisible when installed on the barrel.

About this Material:
The primary material is solid black acrylic acetate. The pen also features a secondary acrylic for the narrow ink-view window in transparent orange acyclic that allows you to monitor the ink level.

About this Inking System:
The Vacumatic
system was introduced in 1932 by The Parker Pen Company, and would come to out-sell the Parker Duofold, which up to then was Parker's top selling fountain pen. The Vacumatic featured a brand new inking system that took several years to develop. However Parker first marketed the pen under the name "Golden Arrow", which was a reference to the also new Arrow clip. But Parker then changed the name to to Vacuum Filler in reference to the pens filling system. And it was one of the first pens that didn't require a sac. Instead, it used a diaphragm, which allowed the entire barrel to be used as the ink Reservoir. While the pen was available in various material, it's best know for the celluloid pattern with alternating horizontal bands of pearlescent and clear.
The Parker information was found at Wikipedia:

The Vacumatic style inking system is available on a variety of pen styles, and the pens can be ordered with or without the ink-view window. The window acrylic is available in clear as well as a variety of transparent colors. Please inquire for the currently available colors. You can review additional information about the Vacumatic style system on my Inking Systems web page HERE.
