Esterbrook Niblet Sea Glass Pocket Fountain Pen

The Niblet Sea Glass is a compact pocket fountain pen from Esterbrook, made from a soft blue-green sea glass acrylic, with a German-made #6 JoWo nib available in extra fine through broad, plus flex and stub.

It's the same beach-glass calm as the Estie Sea Glass, tumbled down to pocket size. The seafoam acrylic shifts between blue and green as it catches the light — a quiet little pen for slow mornings and travel journals.

Everything you love about the Estie, just smaller. The Niblet keeps the curves and character of its older sibling in a clipless, pocket-sized silhouette that slips into bags, pockets, and pen cases — ideal for daily journaling, quick notes, and travel. Inside is the same German-made #6 JoWo nib found in the Estie line, so nibs are fully interchangeable between the two.

Every Niblet comes in a retro-inspired presentation box with a soft felt pen pouch — a lovely gift for yourself or a fellow pen person. One standard international short ink cartridge is included.
