I don't but suspect like most model branded products they are overpriced tatt, those I posted are very good quality for the price. If you want some more expensive but top quality brushes
These are my go to good brushesOur Series 33's are one of the most popular watercolour brush we make. They are a great all-rounder; with an excellent point, and great pigment and water carrying capacity. We describe them as the Rolls Royce of brushes. Kolinsky Sable hair is the best money can buy.www.rosemaryandco.com
