TWSBI ECO Jade Jelly + Bronze Fountain Pen Uncapped on a Jadeite Background

New Arrivals: TWSBI ECO Jade Jelly + Bronze Fountain Pens, Plus New Diplomats!

October 27, 2026

TWSBI’s latest release, the Jade Jelly + Bronze fountain pen, showed up this week and it’s another nice addition to the TWSBI ECO lineup, especially as some of the older ECOs are being retired. Lately, these ECO releases tend to sell out as soon as retailers get them in the door, with relatively long restock windows, so if it interests you I always recommend that people pick one up quickly. The Jade Jelly acrylic is slightly lighter than prior Jade pens TWSBI has released, and appears milky/semi-translucent, similar to the Pink Lemonade (which should return soon).

Diplomat Cobra Fountain Pen and Rollerball Side by Side in Bordeaux and Black Finishes

I’ve also had a chance to get my hands on two new pens from Diplomat: the “Cobra” Fountain Pen and Rollerball, and the Orange Diplomat Viper, available in both a fountain pen and rollerball version. I’m personally a fan of Diplomat’s rollerballs, and opted for a Bordeaux Rollerball Cobra. I’m looking forward to testing this pen out for an extended period as I have some travel coming up and I always take at least one nice rollerball pen with me. As a larger pen, the Cobra immediately feels more substantial than the Viper (for those that found the latter too narrow), and the fountain pen features a standard No. 6 nib in four sizes as opposed to the single-option Viper.

If you would like to see these and more in person, you can visit us in our Nashville store, which is open 1-6pm Thursday and Friday, and from 10am-5pm on Saturday. You can always shop online with us 24/7!
