Overview

The Esterbrook Estie Oversize Sea Glass fountain pen takes its color inspiration from the shores near the brand's birthplace. Its blended acrylic resin is turned and polished, with colors inspired by the glass fragments found along the beaches of New Jersey and New York.

These coastal finds gain their smooth, frosted surfaces through years of exposure to water and weather. Their colors range from amber and green to black, pale pink, frosted clear, and rarer turquoise blue. That varied palette is the reference for the Sea Glass finish, linking the pen's design to the tradition of collecting glass along the shore.

This version has palladium trim and the Oversize instrument format. Its nib is made in Germany by JoWo. It accepts ink cartridges or a converter for bottled ink. Inside the cap, Esterbrook’s cushion closure provides a secondary seal intended to reduce ink drying out between uses.

Questions & Answers

Is the pen made from sea glass?

No. It is made from blended acrylic resin with a polished finish. Sea Glass refers to the colored glass fragments found along the shores near Esterbrook's birthplace, where water and weather gradually give the glass a frosted surface. The pen's color mix draws on those coastal finds.

How does the cushion closure work?

An inner cap provides a secondary seal around the writing end. Esterbrook designed it to reduce ink drying out while the pen is capped.

Can I use both cartridges and bottled ink?

This version uses a cartridge/converter filling system. A cartridge supplies ink directly, or a converter can be used for bottled ink.

What does Oversize mean for this Sea Glass model?

It identifies the larger Estie instrument format. This ESG826 is the Oversize fountain pen, with cartridge/converter filling and the Sea Glass finish.
