Classic Revolve - Fountain Pen (Green M)
As a representative work celebrating the 10th anniversary of the brand, the "Classic Fountain Pen" embodies 10 years of YSTUDIO's experience. After designing a variety of unique writing instruments, YSTUDIO returned to the essence of design to create a truly "pure" fountain pen.
The "Classic Fountain Pen" is the first fountain pen equipped with YSTUDIO’s own nib. The nib across the entire series is embossed with the brand’s original logo from its early days, while the pen body features the new logo for the 10th anniversary, symbolizing the connection between past and future.
The "classic fountain pen series" is finished with a matte lacquer coating, and the pen’s six edges are finely polished to form bright golden brass lines.
Carved from solid brass, the hexagonal pen body follows the brand’s most popular design—pure and simple—with a thicker pen body and just the right balance of weight and sturdiness.
- Box: 185 x 115 x 130 mm
- Refills: one ink converter included (standard international cartridge type)
The color of the brass may change depending on its environment and use, but this is also its unique characteristic. The oxide is harmless. It can restore its original shine by wiping it with brass cleaner. Without any surface treatment, we hope each product will retain its individual marks through the owner’s constant use.
The paint will gradually fade with daily use, revealing the brass underneath, which we call the "brass effect." You can create a personalized brass effect by removing the paint on the surface with the sandpaper included in the product packaging.
INK RECOMMENDATION
For the best writing experience, the manufacturer of our fountain pen nibs, Germany Schmidt, recommends using moderately thick ink. For example, Pelikan, Waterman, Cross inks, etc.

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.
