KOH-I-NOOR Pura Setola hairbrush rectangle 5 Row bristles

KOH-I-NOOR hairbrush. I think this is natural bristles but could be boars head. It is rectangular and has 5 rows of bristles. It does need to be cleaned (see pictures of underneath bristles). Other than cleaning it’s in great condition the pictures of the white background and the description are from the website.
