Winsor & Newton KOLINSKY SABLE BRUSH - ROUND SERIES 7 N°0 : As with so many Winsor & Newton products, their unsurpassed quality can, in part, be attributed to the rigorous selection of only the highest grade of raw materials. So it is with the Series 7 Kolinsky Sable Brush. This tradition began in 1866 when Her Majesty Queen Victoria gave orders that Winsor & Newton, holders of the Royal Warrant produce brushes of the highest possible quality in her favourite size No. 7. The brushes were hand made by craftsmen ensuring only the very finest Kolinsky Sable Hair was used. Since that time artists from all over the world have acclaimed Series 7 as unrivalled amongst sable brushes and to this day carries its world-wide reputation for the finest quality sable available.
