Thank you. Your brushes have very beautiful handles. They look great. Omega brushes usually have cheap plastic handles, but great bristles and low cost. I apologize for the muddled presentation of my thoughts. I write in Russian with the help of a translator.Lovely collection! These will likely last you years, but, if, or more likely when, you want to take the next step, I can’t recommend Zenith highly enough. The majority of their boars are sub-$45 and are truly excellent, as are the Semogue SOC boars.
As for your collection, I can’t tell the knot sizes, but I know that a legendary brush maker and B&Ber uses Omega knots when his customers want a 26mm in one of his handles. So, you have some good quality brushes there.
He also uses the Semogue C5 knots (same knot as the SOC) in his handles; I am the proud owner of four of these creations.
