- In the test, we had four types of chalk with different manufacturing methods and raw material ratios tested blindly. I put only one BLACK in this and thought that I could make a relative evaluation with BLACK.
80% of the test subjects were people who usually use BLACK for rocky areas and competitions, which means that BLACK was selected as the best chalk by the test climbers.
Of course, the subject did not know that there was BLACK in the test chalk.

And the test results were very surprising.
When we evaluated the four types of test results sent from rocky areas all over the country with various parameters, we were surprised to find that 77% of the people chose BLACK as the chalk they felt had the worst friction. That's how it was. Also, of the 12 parameters, BLACK was the lowest in all 9 parameters except for humidity of 45% or less and temperature of 11-15 degrees.

There was a relatively wide variation in the good evaluations, but we selected parts that had similar evaluations even with more extreme parameters, and produced SUPER BLACK with the best raw material ratio and process.
