The weight of words

Born in Taipei, engraved in brass

Since 2012, ystudio has been crafting writing instruments in brass and copper in Taipei. The metal is deliberately heavy to give weight to the gesture. Over time, the surface develops a patina through letters, notebooks, and signatures.

YSTUDIO EXPERTISE

What makes these instruments unique

01

The weight, embraced

Brass gives pens a solid weight that grounds the hand. Writing becomes a deliberate, almost ceremonial gesture.

02

Living metals

Brass and copper darken when touched by fingers. Each pen takes on the patina of its owner.

03

The lacquer and the detail

Lacquered bodies, fine engravings, precise mechanisms: craftsmanship cares for what the hand touches.

04

Designed to last

Standard refills and replaceable parts: instruments made to write for years.

05

A studio, an idea

ystudio advocates for slow writing: slowing down, choosing your words, giving them weight.

06

Taipei, the workshop

The brand was born in the Taiwanese design scene, blending the tradition of writing with contemporary minimalism.
