Collection: Tern Series

Tern Series brings together Thorn Mill’s compact pocket fountain pen design in different materials and finishes.

Every Tern is individually machined on a manual lathe in the Thorn Mill workshop in İznik, without the use of a ready-made pen kit. All models in the series share Tern’s clean, uninterrupted cylindrical form, distinctive Thread Cover Ring (TCR) system, characteristic knurled center section, and compact proportions.

Different metals and surface finishes give each version its own character while preserving the original Tern design.

Every Tern is produced in limited quantities and handcrafted in İznik, Türkiye.
