These are the highest quality round brushes made with Kolinsky sable (Siberian weasel) hair. The brush tips are fine and neatly aligned, and they are very flexible and hold paint well, allowing you to draw fine lines beautifully and for a long time. Brand: Raphael (France) - Quantity: Set of 2 - Model Number and Name: 1) Raphael 88026-2, Kolinsky Round Brush, Extra Long Hair 2) Raphael 88026-4, Kolinsky Round Brush, Extra Long Hair I purchased these about 20 years ago for a tole painting club I was in at the time, and I have carefully stored them in a dark place inside a cardboard box indoors, using them little by little. The activity ended a few years ago, and I have some unused stock left, so I am putting them up for sale. Although they are quite old, there is no deterioration of the packaging plastic. The labels show the price including the 5% consumption tax at the time (see photo), but the current price including tax is 2.5 times or more, so this set is a good deal. Thank you for looking.
