Know before you buy
The GMK Mutagen set is crafted from high-quality ABS plastic using a doubleshot molding process. This ensures the legends remain crisp and will not fade over time.
These keycaps are designed for Cherry MX-style switches, which are the standard for most mechanical keyboards. If your board uses this stem type, they will fit.
The keycaps are infused with specialized pigments that absorb light and emit a glow in low-light conditions. For the best effect, expose them to a bright light source before moving to a dark environment.
The Cherry profile is a popular, sculpted keycap shape known for its comfortable, ergonomic typing experience. It is slightly shorter than the standard OEM profile, making it a favorite among enthusiasts for its consistent feel.
No, this product is a keycap set only. You will need to provide your own mechanical keyboard base and switches to use these caps.
Yes, the slimy translucency of the material will allow your keyboard's backlighting to diffuse through the caps. This creates a unique, moody aesthetic that complements the chemical-themed design.
