These are 6 oil paint brushes from the IZUMIYA era. I don't know the type of hair, but it's soft. Although the feel of use may vary from person to person, they might be better than current imported brushes. The size is 10, and the brush length is about 33cm. They are unused, but they are old, so there are scratches and minor abrasions due to aging. Please refrain from purchasing if you are sensitive to such things.
