Overview

The Esterbrook Estie Sea Glass fountain pen takes its inspiration from the shores near the brand’s birthplace. Its green resin and PVD gold trim recall the coastal glass that gives the collection its name, bringing a seaside theme to this version of the Estie.

Sea glass is glass weathered by the water and collected along the shore. Its palette can range from amber and green to black, pale pink, frosted clear, and rare turquoise blue—a variety of colors that inspired the collection rather than a single uniform shade.

This version has a stainless steel nib with a PVD gold finish and accepts standard international cartridges or a converter for bottled ink. The screw-on cap incorporates Esterbrook’s cushion closure inner cap to help keep ink wet and reduce dry-out between uses.

Questions & Answers

What does the Sea Glass name refer to?

It refers to weathered glass found along the coast. Esterbrook drew on the shores near its birthplace and the varied colors of sea glass, from amber and green to pale pink, frosted clear, and rare turquoise blue. This version has a green resin finish with PVD gold trim.

Can I use cartridges as well as bottled ink?

Yes. This Sea Glass accepts standard international cartridges or a converter for bottled ink. It is the cartridge/converter version of the Estie; the piston-filling Sea Glass is a separate model.

What is the cushion closure inner cap?

It is the inner closure within the screw-on cap. Esterbrook designed it to help keep ink wet and reduce dry-out when the fountain pen is capped between writing sessions.

Esterbrook Estie Sea Glass Fountain Pen

Esterbrook makes very good nibs at a resonable price. This particular pen is easy to fill and grip to write with. I'd give it an A+.

Thank you for sharing your opinion, it’s a pleasure to know that you’re so happy with your Esterbrook.

Stunning....

Wow, firstly the appearance of the pen is more beautiful in person, but the nib is perfection. I already own the estie in nouveau bleu and adore the writing experience but I wasn't sure if i'd just gotten lucky with the nib.....it seems not. The nibs are smooth and, to be honest, superior to others I have (with the exception of my Opus 88) in my collection. I highly recommend this pen.

Hello Abi!
Your description has us smiling—we're absolutely delighted to hear you!
Thank you for such a heartfelt and strong recommendation!
Happy writing!
Warm regards,

Not a great experience

I bought this pen assuming I would receive the only colour I have seen this site advertise in respect the Esterbrook Estie Sea Glass Fountain Pen. What I received was an extremely pale version of the colour advertised by them. When I contacted Iguana, they stated that this make and model comes in all types of shades and that those who tend to buy it ask that the correct colour be sent to them. I asked if they could replace the pen, only to be told that I would be charged £9.80 x2 for shipping. They did not take responsibility for not advising that this pen may not arrive in the colour ordered and compounded that by charging shipping fees as ‘technically’ this was not a defect. I advised I would return the pen and would like a refund. They explained I would only be charged £9.80 but on receiving notification of the refund today, they have charged £19.80. Needless to say, I won’t be using them again. They were quick in their responses but did not take responsibility for what i deem to be their mistake.
