1. Keychron Q4 and V4 share the same keycap size as the K12, so this keycap set is also compatible with Q4 and V4.
2. The Backlight Shine Through version is designed to shine through the north-facing backlight keyboards (e.g.: K12), so the shine-through effect on the south-facing backlight keyboards (e.g.: Q4 and V4) may not be that visible.
