Know before you buy
The Hiragana version features traditional Japanese sublegends, while the Dark Kaiju version utilizes unique scripted sublegends. Both sets share the same premium ABS construction and Cherry profile, allowing you to choose based on your preferred aesthetic.
These keycaps are designed for Cherry MX switches and MX-style clones. They feature the standard Cherry profile, making them compatible with the vast majority of custom mechanical keyboards on the market.
GMK uses high-quality, thick 1.5mm ABS plastic, which is known for its crisp, sharp legends and satisfying sound profile. While ABS can develop a slight shine over time with heavy use, the double-shot molding process ensures the legends will never fade or wear off.
The Latin alphas kit provides an alternative set of keycaps that feature only English characters, removing the sublegends for a cleaner, more minimalist look. It is an optional add-on for those who prefer a traditional layout.
The Cherry profile is a sculpted keycap shape that is shorter than the standard OEM profile. It is widely considered the gold standard for enthusiasts due to its comfortable typing angle and consistent, deep sound signature.
