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 November 2023: The Nanga is now available with a new Vacumatic style inking system! The Vacumatic barrel is the same length as the standard Nanga barrel but with about a 1 1/4" long blind cap that covers the vaccum button. So now there are FIVE inking system options available: 1) the standard C/C; 2) Eyedropper with a custom fitted o-ring; or 3) Bulb-filler; 4) Button-filler; 5) the new Vacumatic style filler. For more infomation on the system, see the web page named inking-systems under the Other Items drop down button.

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 a type of acrylic called Cellulose Acetate (CA). CA is one of the older types of acrylic. As such, it has different characteristics than some of the more modern acrylics (such as acrylic acetate or alumilite). CA also has a very distinct smell when turning it, so you know if you're turning the real thing. Its very nice material to work with-- it turns like butter and has a warm soft feel (similar to alumilite). The only issue I had was with the sanding in preparation for the polishing. It clogged the sandpaper very easily, so it was hard to work through the different sandpaper grits. So I ended up sanding the parts almost completely by hand. I also should include the fact that cellulose acetate is much more expensive than other acrylics. A 20mm square x 200mm long blank cost $20.00 each, and the Nanga Magnum requires TWO ($40.00 total--but the standard size Nanga only requires one). In comparison, the same amount of acrylic acetate would only cost about $12.00. But I think you'd be hard pressed to find another acrylic that would give you the same depth in the color or the pattern as you get with cellulose acetate. The color is called 'Arcola'. It has a transparent brown base with some type of reflective material that creates the pattern, which is only visible on opposite sides (see the capped photo's above). Arcola is said to be modeled after the famous Omas Arco acrylic, but the pattern isn't very similar.

NOTE: I also made a Nanga Magnum using another cellulose acetate called Verdigris. You can check it out HERE.
