This is a brush from Jitsueido, a brush maker in Hiroshima. The tip of the small brush is slightly frayed. Please check the photos for the size of the brush tip. Although it is an unbranded item, it is a natural brush made using animal hair. I am unsure whether it is weasel hair or horse hair. I purchased the set of 2 for 2000 yen. Thank you.
