The yin and yang inside Blue and Black Koi resin keycap

The pattern on Koi fish is a metaphor for yin and yang – the dualism of the world and the main theme for our Koi keycaps.

There are two Blue and Black Koi artisan keycap versions. The first one has one black dot of yang on the white body of yin, while on the other Koi fish, the black dot has expanded.

They both swim inside the Blue pond and that completes the picture of the Blue and Black Koi keycaps. When the fishes dive deeper, the white will gradually disappear and all that is left to be seen is the blackness.

Just like how the yang is inside the yin and then takes up the yin. Our Blue and Black Koi resin keycaps are painted meticulously in a 6-day process to bring out the beauty of the world balance’s symbolism to your keyboard.

We cannot get enough of the dualism metaphor so here is a huge collection of Koi keycaps from Hirosart. Moreover, if you are into artisan keycaps, visit us at this link.
