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 pen is called the MAGNUM because it's a LARGER VERSION of the standard size Nanga. It was a special order, with the client giving me the LENGTH (6 1/2"), then requesting that the rest of the pen be size proportionally larger. So EVERYTHING but the nib is larger (including the capping threads) by 13%. The pen includes the same unique forward mounted threads as the original, but in a slightly larger size to fit the rest of the larger proportions. The MAGNUM also includes a feature not found on the standard Nanga-- the client wanted to use his as an eyedropper, so I added an o-ring to seal in the ink.

About this Material:
This material is not an acrylic, but actually a type of lava (yes, rock from a volcano) composite material. It comes from a company that makes pen blanks using various natural materials such as lava, metal and carbon. They offer the lava in several other colors. I'm not quite sure of the actual contents--the sellers discription seemed a little ambiguous, combining all the various materials the company offers into a single paragraph to cover the various materials used (see below). The Lava is comprised of a special material called M3, which is short for Macro-Molecular Materials, the same type of materials used for everything from the Stealth Bomber to the International Space Station. It's brittle like some acrylics, but not near as hard as some of the exotic materials can be. This M3 Lava also has pearl in it, so it has a nice sparkle once it is polished. One other thing to note that I found with the M3 Lava was its WEIGHT-- it's about 45% heavier than most acrylics. So if you prefer a heavy pen, you may like this material.

Description of the Black & Red Lava from the suppliers website:
"Real Metal Blanks That Turn on a Wood Lathe! Create stunning heirloom quality luxury goods with M3 Mokume* composite blanks. Add a whole new dimension to your art by creating with magnificent materials exhibiting spectacular wood grains (Mokume), patterns and surface characteristics that both mesmerize and inspire. Produced with exotic natural elements (metals, lava, carbon) that have been transformed by the M3 macro-molecular process enabling them to be worked with standard tooling, finished easily to a gem quality surface and will literally last forever."

*Mokume is short for Mokume-gane (木目金 Mokumegane), a Japanese metalworking procedure which produces a mixed-metal laminate with distinctive layered patterns, as well as that laminate itself. Mokume gane translates closely to "wood grain metal" or "wood eye metal" and describes the way metal takes on the appearance of natural wood grain. Mokume gane fuses several layers of differently colored precious metals together to form a sandwich of alloys called a "billet." The billet is then manipulated in such a way that a pattern resembling wood grain emerges over its surface. If you'd like to read more about M3 and the process, then check out this link:

Similar to Cumberland Ebonite...
This was the first time I used this material. But once I rounded the blanks I realized that the color was familiar somehow. Eventually it dawned on me that the colors were very similar to Cumberland Ebonite. The photo at the right shows a comparison of the Black & Red Lava and Cumberland Ebonite (from SEM).
