Ducky One 3 Classic SF Keyboard Gaming USB US English Black White

The Ducky One 3 Classic SF Keyboard is a wired 67-key mechanical keyboard in a black-and-white finish, designed for gaming and everyday typing. It uses true PBT double-shot keycaps with a frosted surface for lasting legends and resistance to shine and stains. The keyboard features a dual-layer PCB, detachable USB Type-C cable, Kailh hot-swap sockets, multi-layer acoustic padding including an EVA foam layer under the PCB, and adjustable feet that provide three typing angles. RGB backlighting and a sleek bezel complete the design for reliable connectivity and customizable illumination.

Advantages

True PBT double-shot keycaps preserve legend clarity and resist wear and shine over long-term use. Hot-swappable Kailh sockets enable quick switch changes without desoldering. The optimized weight distribution and lowered case height increase stability during intense use. Multi-layer acoustic padding and an EVA foam layer under the PCB improve sound profile and reduce unwanted noise. Dual-layer PCB improves signal stability and longevity, while USB HID at 1000 Hz polling ensures responsive input.

Suitable for

• PC gaming where quick response and durability are needed
• Mechanical switch experimentation and customization (hot-swap)
• Typing and office work requiring a stable, compact layout (67 keys)
• Users who want RGB lighting and adjustable keyboard angles
