Esterbrook Niblet Fountain Pen Sea Glass

Esterbrook Niblet Sea Glass is a pocket fountain pen designed to go with you anywhere, combining style and practicality. Its compact shape, inspired by the Estie line, retains the elegant curves of the original model, reimagined in a portable format for notes, travel, or everyday use.

The Sea Glass color captures the delicate beauty of ocean-tumbled treasures, with a combination of translucent blues, greens, and whites that evoke the freshness of a sea breeze and the calm of rolling waves. A soothing visual effect, inspired by the frosted glass fragments found on beaches.

Made of hand-turned acrylic resin, the Niblet Sea Glass features soft, harmonious swirls, accented by a gold-plated roll stop in place of a traditional clip — a vintage touch that’s both elegant and functional.

Inside, the pen is fitted with a trusted Jowo #6 nib, the same as in the Estie line, offering a smooth, reliable writing experience. It is compatible with specialty and custom nibs. The filling system includes a custom mini converter and also accepts standard international cartridges. The cap features a threaded closure and can be posted on the barrel while writing for added convenience.

Each pen comes in a retro-style box with an Esterbrook-branded felt pen sleeve, ideal for carrying or gifting in style.

A fountain pen that combines beauty and functionality, perfect for those who write with character and ease.
