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
The weight, embraced
Brass gives pens a solid weight that grounds the hand. Writing becomes a deliberate, almost ceremonial gesture.
Living metals
Brass and copper darken when touched by fingers. Each pen takes on the patina of its owner.
The lacquer and the detail
Lacquered bodies, fine engravings, precise mechanisms: craftsmanship cares for what the hand touches.
Designed to last
Standard refills and replaceable parts: instruments made to write for years.
A studio, an idea
ystudio advocates for slow writing: slowing down, choosing your words, giving them weight.
Taipei, the workshop
The brand was born in the Taiwanese design scene, blending the tradition of writing with contemporary minimalism.
