Purity Brush, Size 4 Kolinsky Sable Roymac

• Size 4 is the most practical mid-range size in the Purity range — enough paint load for broader applications while retaining the fine tip response that Kolinsky sable provides
• Natural hair point return is maintained through years of careful use, making this a long-term investment for watercolour artists
• A practical size for anyone upgrading from student-quality synthetic brushes to professional Kolinsky sable performance

Pure Kolinsky sable hair, FSC certified wood handle. Store with cap on when not in use.

Why choose Kolinsky sable at Size 4 rather than a smaller size?

• Size 4 is where the Kolinsky sable performance becomes most practical for general studio watercolour — handling detail, washes, and mid-scale painting in the same brush. The moisture holding and point return that define Kolinsky sable are most useful at working sizes.

How does the Purity range differ from the Revolution range?

• The Purity uses natural Kolinsky sable. The Revolution uses synthetic taklon engineered with surface pock marks for improved performance. Kolinsky sable remains the performance benchmark, particularly for watercolour. ---
