YStudio spring ballpoint pen Classic Revolve black

The Classic Revolve ballpoint by Ystudio is crafted from black lacquered brass – a solid, cool material that feels noticeably heavier than plastic or aluminium. At 42 g, it sits satisfyingly in your hand. The twist mechanism with an exposed coil spring on the cap is the visual hallmark of the series and its operating principle: extend the refill by twisting, write, twist back. The Brassing Edition is deliberately conceived as a living object – the black lacquer changes over time, revealing the brass beneath.

Features

• Solid brass, black lacquered: The body is entirely brass with a matt black lacquer finish. The material brings weight (42 g) and thus stability when writing – the pen glides across paper effortlessly thanks to its inherent momentum, requiring no force.
• Brassing effect: The black surface wears away in daily use at the edges and grip zones, exposing the golden brass beneath. Each piece develops its own unique patina that reflects your personal handling. The included abrasive paper lets you accelerate this process deliberately – sand specific areas to emphasise what the brass is.
• Twist mechanism with spring: The characteristic coil spring sits visibly at the top of the pen and forms part of the extension mechanism. Twisting requires deliberate hand movement – no accidental extension in your pocket.
• Schmidt P900 M large-capacity refill (black): The included refill in G2 format features a metal shaft, stainless steel tip with TC ball, and writes in medium line width. The P900 ink is document-permanent – resistant to water, light and common chemicals. Thanks to excellent shelf-storage properties, the refill stays ready to write for long periods without cap seal.
• G2 compatibility: The barrel accepts all large-capacity refills in the international G2 format (Parker system). Beyond the included Schmidt P900 M, many other G2 refills are compatible – with different line widths, colours or ink systems.

Use & Tips

• Shape the brassing actively: The included abrasive paper works well on specific areas – grip zone, cap, edges. If you prefer to wait, everyday use will shape the patina naturally. Both approaches are equally valid.
• Refill selection: The Schmidt P900 M writes with satisfying flow and medium fineness. For a finer line, switch to the P900 F (fine). All G2 large-capacity refills fit – oil-based refills produce drier, more opaque writing, while softer-writing systems place less stress on paper.
• Paper: The P900 M works particularly well on smooth, calendered paper – crisp writing, no feathering. On slightly rough paper, the medium line width produces a somewhat broader, warmer line.
• Brass care: Exposed brass oxidises over time and darkens – this is desired and part of the design. If you wish to maintain or refresh the brass shine, gently treat exposed areas with brass polish.
• Weight as a writing aid: At 42 g, this is substantial for a ballpoint. It has a positive effect on calm, even writing over longer distances – the pen practically guides itself.

For Writing Instrument Enthusiasts

The Classic Revolve ballpoint is part of the "Weight of Words" series – a design statement by Ystudio (Taiwan) that positions brass as a material against the transience of digital communication. Brass is not an inert material: it responds to touch, humidity and time. The black lacquer of the Brassing Edition serves as a starting point that can be transformed – slowly through use or actively using the included abrasive paper. The twist mechanism with exposed coil spring is made visually explicit: mechanics as aesthetics. The Schmidt P900 M is a G2 large-capacity refill in Parker system with document-permanent ink and TC writing ball – a refill designed for writing instruments without cap seals, which suits this pen's cap-free twist mechanism perfectly.
