Kolibri Flat Cat’s Tongue Brush Series 1680SQI – Precision and Elegance for Watercolour Art
The Kolibri Flat Cat’s Tongue Brush Series 1680SQI combines traditional craftsmanship, German precision, and modern materials to deliver a superior painting tool. Designed primarily for watercolour techniques, this flat brush with a rounded tip (filbert/cat’s tongue) excels at distributing colour evenly, creating natural transitions, and capturing fine details with ease.
Made from advanced synthetic squirrel hair fibres (SQI LINE), the brush offers exceptional softness, flexibility, and water retention, meeting the needs of both professional and hobby artists. Completely vegan-friendly, it provides ethical quality without compromising performance.
Key Features
The brush’s synthetic SQI fibres perfectly mimic natural squirrel hair, providing excellent water and pigment absorption while remaining soft, resilient, and easy to clean. The cat’s tongue (filbert) shape allows for precise line work at the tip and broader strokes with the flat part, making it versatile for a variety of techniques.
A short, lacquered cedar handle in red metallic finish with a silver ring provides excellent balance and control. The seamless nickel ferrule secures the fibres firmly, ensuring long-lasting durability. Its ergonomic and elegant design combines functionality with aesthetic appeal, making it a pleasure to use during long painting sessions.
