The Diplomat Viper Fountain Pen in Green.

Thursday Drops: Green Diplomat Vipers, Big Notsu Cards, and More Fountain Pen Restocks

September 4, 2025

I returned from the San Francisco Pen show to a box of the newly released Green Guilloche Diplomat Viper, which we have in both fountain pen and rollerball formats! For those unfamiliar with this pen, the Diplomat Viper is a hooded-nib fountain pen that features a single nib width (fine/medium) which is perfect for my own everyday writing. While I chose the Blue fountain pen, all of these colors are great.

We have additional stock of the TWSBI Diamond 580 ALR Affogato + Onyx, as well as newly arrived restocks of the Lamy 2000 in fountain pen, rollerball, ballpoint, and even mechanical pencil formats. Finally, Notsu is back with large-format index cards (per Tuesday’s post), and all of the Roterfadens we brought home San Francisco are back in inventory if you didn’t get to visit us at the pen show. Happy Shopping!

We are open this week from 1-6pm on Thursday and Friday, and from 10am-6pm on Saturday. Come see us in person at our Nashville location, and keep track of updated hours on this page here.

  1. Diplomat Viper Fountain Pens and Rollerballs in Green. The latest Diplomat Viper release is here, in a much-anticipated green color. We also have a full restock of the other three colors.

  2. TWSBI Diamond 580 ALR Affogato + Onyx Fountain Pen. A sleeper hit at this year’s San Francisco Pen Show, many people came by the tables just to see TWSBI’s latest. The Onyx Trim really sets off the dark brown anodization on this 580 ALR. The Caribbean Blue + Onyx is also stunning, and it’s also been a sleeper favorite.

  3. Roterfaden Taschenbegleiters in A5 and B6. All of the Taschenbegleiters that we took to San Francisco and did not sell (as well as those that didn’t make the trip) are now back into inventory as of this morning.

  4. Sunderland Machine Works MK1 Machined Rollerball. One of my favorite non-fountain pens, these machined rollerballs take a range of gel refills (G2, Energel, Sarasa) with minimal hacking, and will also accept the threaded Montblanc-style rollerball and fineliner refills. While our store custom edition is currently on hiatus, we carry the range of standard Sunderland finishes.

  5. Pilot Custom 823 Fountain Pens. We’ve restocked on the Pilot Custom 823 Fountain Pen in Amber, Smoke, and Clear, and between the three finishes I believe we have most nib sizes available. The Custom 823 has long been one of our “workhorse” fountain pens for everyday writing, mainly because the vacuum-filling system uses a valve shut-off feature to allow you to travel without fear of leaks.

  6. Lamy 2000 Ballpoints. The ballpoint version of Lamy’s flagship fountain pen is not only reasonably priced, but comfortable for longer writing sessions and now compatible with the M17 Jetstream refill, which we offer in either .5mm or .7mm tip sizes.

  7. Lamy 2000 Blackwood and Taxus Ballpoints. Did you know that the Lamy 2000 comes in two polished wood finishes as well? These take the same range of refills as the standard pen, and have slightly more heft than the Makrolon.

  8. Oversized Notsu Notecards. Notsu’s excellent ink-friendly notecards are now available in a larger 5x7 format, and we have also restocked on most other sizes and layouts.

  9. Colorverse “Top 3” Fountain Pen Inks. Colorverse released the top 3 inks from last year’s Colorvent Advent Calendar, and we are now happy to offer them in 50ml bottles. The three colors that won the vote were Christmas Star (Glistening/Shimmer), Pulsar Pulse (Sheening), and Milky Way (Glistening/Shimmer).

  10. Taccia Tsuchi Returns! Years ago, I had tried Taccia “Tsuchi”, a darker golden brown based on the color of wheat. Despite thinking this one had been discontinued, I found it and have added a few bottles.
