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

The Ducky One 3 Classic SF is a 67-key wired mechanical gaming keyboard designed for stable performance and customizable lighting. It comes in a compact SF layout and features a detachable USB Type-C cable, hot-swappable switch sockets, and a dual-layer PCB for improved signal stability and durability. The keyboard uses true PBT double-shot keycaps with a frosted finish for long-lasting legends and resistance to shine and stains.

Advantages

True PBT double-shot keycaps ensure legends never fade and provide a textured, stain-resistant surface suited for prolonged use. Optimized weight distribution and lowered case height improve stability so the keyboard remains steady during intense typing or gaming. A multi-layer padding design and an EVA foam pad under the PCB enhance acoustics and reduce unwanted noise. Kailh hot-swap sockets allow fast, tool-free switch changes. Detachable USB Type-C connectivity with 1000 Hz polling supports responsive input. The dual-layer PCB offers longer lifespan and reliable signal handling with support for N-key or 6-key rollover, and two-step feet provide three tilt angles to fit different ergonomic preferences.

Suitable for

• Competitive and casual gaming where stable, responsive input is required
• Enthusiasts who change mechanical switches frequently
• Users who prefer durable, non-shiny keycaps for heavy daily typing
• Desktop setups needing compact 67-key (SF) layout with RGB customization
