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:

As you can see from the photo's, this pen is a BULB-filler. The name describes how the pen works to fill it with ink. A bulb-filler fills very similar to a button or lever filler pen, but instead of using a button or a lever to compress the internal ink sac (that then holds the ink), you compress a bulb to bring the ink into the pen barrel directly. The bulb is actually the same as an ink sac used in a button or lever filler pen, it just doesn't hold the ink this time.

For instructions on how to fill a bulb-filler pen, SEE THIS LINK.

This pen is also shown with an optional see thru 'ink window', that makes it easy to see how much ink is remaining in the pen, as well as when you have it fully filled. The ink window acrylic is available in various transparent colors, or in clear acrylic. So you can color coordinate the window with the main material. The ink window isn't necessary, just a nice feature. So if you don't care for the look, you can order a bulb-filler without a window.

About this Material:
The main green color is called Malachite Stonite polyester. Stonite is the brand name, and Malachite is the color. Malachite is a green & black semi-precious stone, so the acrylic is suppose to mimic the stone. It is hard to see in the photo's, but the green isn't a totally solid color, but has some faint black streaks running throughout. It also slightly transparent, so the thinner the material becomes, the lighter the green will look. The ink window is yellow transparent Alumilite acrylic.
