Why is "koyomo" superior? While the outstanding qualities of "koyomo" are a well-known fact among calligraphers, the reason for these qualities was not very well known. In order to find out more about them, Tsubokawa Mohitsu Corp. had some "koyomo" got hair scientifically evaluated with the cooperation of the "Hiroshima Prefectural Agency of Technology, Seibu Industrial Technology Center." The evaluation comparatively verified the qualities of the "koyomo" based on scientific data regarding other raw hair materials that are commonly used in makeup brushes at the moment, such as "normal goat," "grey squirrel," "horse," and "deer." Please find the results below.

"Goat" and "deer" hair, which are commonly used in modern makeup brushes, have thin layers and a large number of cavities. "Horse" hair, which is said to be harder, has thicker layers. The same goes for our "koyomo," which has thick layers and a concentrated structure at its core, which gives it full body and makes it difficult to break.
