Clear Orange, Clear Green, and Brass Gold — three semi-translucent matte pens that embody YSTUDIO’s signature minimalism and refined craftsmanship.

The matte surface diffuses each color, highlighting the warm sheen of the brass barrel beneath. Drawing inspiration from Taiwan’s shifting landscapes: morning mist, twilight glow, and soft daylight—the design unveils a layered elegance that echoes the quiet beauty of nature.

Crafted with a hexagonal body that recalls the joy of holding your first pencil, this rollerball pen combines perfect balance with a smooth water-based refill for effortless writing. A built-in spring mechanism adapts to every stroke, reducing resistance and adding flexibility for a fluid experience. The cap’s inner seal prevents ink from drying, while its crisp metallic click adds a satisfying sensory detail.

Compatible with standard refills and designed with a convenient twist mechanism, it ensures quick and easy replacement—making every detail as functional as it is refined.
