Full Acrylic 75% Hot-swappable Keyboard
The CK75 is a hot-swappable mechanical keyboard with a solid transparent acrylic case. It not only has a beautiful unique design and also delivers a premium solid feeling. The keyboard features south-facing LEDs and is fully hot-swappable with 3-pin or 5-pin mechanical switches. With the CK75, you can easily swap your stock switches for any other colored or MX-style switches with no soldering required.
Gasket Mounted Mechanical Keyboard
The CK75 takes high-quality gasket structures. The keyboard adds a poron foam switch pad and a sound-absorbing silicone pad on the top and bottom edges of the board and PCBA. High-quality gaskets and silicone in gasket-mounted keyboards absorb the impact of each key, creating a smoother, cleaner, and more flexible typing experience.
Large Battery Capacity & South-facing RGB Backlights
The CoolKiller CK75 features a variety of default RGB effects that you can easily change it. South-facing PCB can make the keyboard RGB smoother and brighter. The compatible software is available for those who love more DIY settings. Built-in 3750mAh battery, the CK75 lasts for 25 hours with full lights on and 90 hours when no RGB.
2-Layer Transparent Keycaps KSA Profile
The CK75 designed their keycaps with 2 layers to achieve both a premium typing experience and a translucent appearance. The typing layer is made with high-quality double-shot PBT, which is more durable and oil-resistant. Dye sub-manufacturing ensures the colorful legends are clear and anti-fading. The KSA profile of keycaps offers an ergonomic typing angle and height, suitable for both gamers and typists.
Coolkiller Custom Switches
The Ice Blade switch is a tactile switch that is pre-lubed.
