Esterbrook - Pendemonium!

Updates - **Scroll down to see our latest updates**

Esterbrook fountain pens listed below have fine point nibs, additional styles of nibs are listed in the Renew Point table after the pen listings.

Esterbrook Cartridge Filling fountain pens - We include an empty cartridge with each of these pens. Please note that there is NOT a currently made cartridge that fits these pens. We sometimes have available empty Esterbrook cartridges that can be refilled with a syringe. We also sometimes have available retrofitted convertors for Esterbrook cartridge fillers. Please email for further info.

Esterbrook Ballpoint Pens - To date, we know of NO ballpoint refills being manufactured that will fit into Esterbrook ballpoint pens. Once in a blue moon, we turn up a batch of Esterbrook BP refills that still write, but it is a rarity! There is a rather time intensive and cumbersome way to bring Esterbrook BP refills back to life which involves removing the old "ballpoint tip", replacing with a new tip and removing any and all leftover ink in the old refill tube. If you'd like full details on how to do this, click here to view the instructions.

J Series Fountain Pens and Pencils

Esterbrook manufactured the J series fountain pens from the late 1940's through the late 1950's. The J series was made in three sizes; J Full Size, LJ Long Slender and SJ Short Slender. Colors available were solid black, marbled red, marbled blue, marbled gray, marbled brown (copper color), marbled green and solid olive drab.

Non-J Series Fountain Pens and Pencils

Here you will find earlier Esterbrook writing instruments: Dollar Pens, Two Hole Clip pens as well as later Esterbrook items such as aerometric fillers, plunger fillers and cartridge fillers.

Desk Sets, Dip-Less Inkwells and Desk Pens

Esterbrook desk sets and inkwells are some of my favorites for everyday use. Desk sets are heavy and well balanced making it difficult to tip them over, who's going to complain about fewer ink spills? The Dip-Less inkwells hold LOTS of ink and your pen is always ready to write. Black was the most common color used for Esterbrook desk sets and inkwells. Other colors were produced as well, but are more difficult to find have become very desirable by Esterbrook collectors.

ES845 $70

Esterbrook Desk Set, black porcelain desk set with the raised grey pearl trim ring.  This style of trim ring did not survive the years well, many are found split, most are found with some sort of staining. 

This one is NOT split,  but does have some light crazing on the inner edge which is ink stained. 

Included is a lever fill Esterbrook black desk style fountain pen with clear taper fit with a No. 1550 Renew Point firm fine point. Aside from the light crazing to the trim ring, very good condition.  Early set, not as easy to find as they once were.  

ES977  $50

Esterbrook black and clear taper desk style fountain pen with 9555 Gregg Shorthand Renew point. FP measures 6.75inches long.  The base is not an Esterbrook, in fact we don’t know who made it, but it definitely is from same era and just has that Esterbrook look – black porcelain with raised ribs down the center.  Great Art Deco design. Base measures 3.5 x 2.5 at base, height at rear is 2.25 inches. Excellent condition and the Esterbrook pen looks right at home in this desk base and fits just right, too. 


ES995 $60

Esterbrook Model 444 DipLess Desk Set, clear glass inkwell base with with grey inset. Black bakelite top unscrews to fill up the inkwell, holds over 1 ounce of ink.

Esterbrook Model 447 DipLess Inkwell with DipLess Fountain Pen, ca, late 1950s - early 1960s.

Gasket Replacement Info for Esterbrook 407 Style Inkwells

If you have an inkwell that looks like the one above, you have an Esterbrook model 407. These have a red gasket set inside the bottom glass portion of the inkwell that sometimes goes missing over the years. The proper replacement gasket is as far away as your local hardware or plumbing supply store! Look for the "Flush Valve Seal" for a Mansfield #210. They're even red like the originals!

The last batch we bought came from our local Kempker's Hardware Store, a True Value outlet, and this is the info from the package:

  • Danco Flush Valve Seal for Mansfield #210
  • Two other numbers on the package: 340 and 88096
  • The UPC code is 3715588096

Specs of the Esterbrook Model 407 gasket:

  • Inside diameter is 55mm

Esterbrook Memorabilia

ES-789 Esterbrook Stick Pin $10

Reproduction of a turn of the century Esterbrook lapel pin, sometimes referred to as stick pins was made to hand out to convention attendees. The pin measures 1 3/8 inches long and vintage Esterbrook nib is a bronze No. 048 Falcon - nib is original, not a repro. The top of the pin where the nib hangs from is a bright polished brass with Esterbrook inside an elegant little swirled border frame. I happen to have one of the original one of these pins for comparison's sake and the repro is very well done. I bought the last of these that were made - get yours today, far more reasonable than the originals! Perfect for your pen show lapel. New and never pinned!

ES945  $10

Esterbrook P.E. No. 2 Erasers - READ FIRST:  These cool old erasers in original small box of 4 inside the original outer box DO NOT ERASE!  These are a nifty old collectible that you don't see often.  Two small original red and white boxes inside the master box. Very minty condition.
