The Kaërell is a versatile synthetic brush that works across both acrylic and watercolour, making it a practical choice for painters who move between mediums or want a single brush family that covers a wide range of techniques. The fibres are soft enough to handle watercolour without scratching the paper surface, and resilient enough to hold their shape through the repeated loading and cleaning that acrylic work demands. The worn round format (a rounded, slightly splayed tip) is particularly useful for blending and soft edge work where a standard round would produce too precise a mark. Rounds, flats, fans and a large spalter for varnish complete the range. For the full Raphaël brush selection, visit Raphaël Watercolour Brushes, Raphaël Acrylic Brushes or browse all Raphaël.
