Ducky One 3 Classic SF Keyboard Gaming USB Mechanical 67 Keys RGB

The Ducky One 3 Classic SF Keyboard is a wired 67-key mechanical keyboard designed for gaming and daily typing. It features true PBT double-shot keycaps with a frosted surface that resists shine and stains, a detachable USB Type-C cable, hot-swappable Kailh sockets, and customizable RGB backlighting. The keyboard uses a dual-layer PCB for improved signal stability and supports N-key or 6-key rollover. Three tilt angles are available via two-step feet.

Advantages

Keycaps are made from true PBT using a double-shot molding process so legends remain durable and do not fade. The lowered case height and optimized weight distribution increase stability during intense use. Multi-layered internal padding and an EVA foam layer under the PCB provide improved acoustics and reduce unwanted noise. Kailh hot-swap sockets allow easy switch replacement without soldering, and the detachable USB Type-C connection supports a 1000 Hz polling rate for responsive input.

Suitable for

• PC gamers seeking a compact 67-key layout with reliable performance
• Users who want hot-swappable mechanical switches for customization
• Typists who prefer durable PBT keycaps with long-lasting legends
• Anyone needing a stable wired connection with 1000 Hz polling
