The Raphaël Medium Brush, size 2 is a brush from Pure Kolinsky Sable Round 8404 range. It is a high quality painting brush that holds the perfect tip for long time.
As a painter, gamer and general hobby enthusiast with over 25 years of experience I've learned that the most valuable commodity is time. And also there's no greater regret than losing precious hobby time with low-quality tools.
If you are painting miniatures you really want a proper painting brush that holds the perfect tip. Otherwise, you simply can't paint any details. It's not possible.
These Raphaël brushes cost are not cheap, but they endure for a long time. I have brushes I'm using for more than three years and they are still just fine.
The brush is manufactured by Raphaël company (France), the oldest fine art brush maker in Europe.
