Artisan KREX brushes are amazing! The KREX fibres are an exclusive blend of KREX® filaments composed of several monofilament types of differing lengths, characteristics and colors (blue and white). These brushes are virtually Indestructible and super easy to clean. The KREX fibres hold an incredible amount of paint, lay the paint down with virtually no brush strokes perfect for use with Chalk & Mineral Paints. With a traditional beechwood handle whats not to love about these.
