International Klein Blue (IKB) is the unique color born by one of the greatest artists in history - Yves Klein.
Yves Klein was a French artist and an important figure in post-war European art. He was a leading member of the French artistic movement of Nouveau réalisme founded in 1960 by art critic Pierre Restany. Klein was a pioneer in the development of performance art and is seen as an inspiration to and forerunner of minimal art.

This is the blue people started to appreciate after more than half a century since its birth, its minimalist vibe and its visual impact comes from its heavy reliance on ultramarine.

PBTfans Klein Disclaimer

1. Since all the sub-legends on this set are produced by the UV printed method, their acceptable tolerance range is plus or minus 0.3 mm.

2. Since it is finished with ABS material, the texture of the sub-legends might have tiny concave-convex. This will not be visible without a magnifying glass.
3. The sub-legends on the ABS keycaps are made through the UV printing process with wear-resistant and scratch-resistant tests, and they are not easy to be wiped off.
However, large and consistent amounts of hand sweat, oil, longtime use, or chemical composition may still damage the sub-legends.
