This ProDec Synthetic Paint Brushes are specially designed for painting delicate finishes like architraves, mouldings, and detailing around doors and windows. The synthetic fibres of the brush heads allow for more control than some other brushes, ensuring a more even application and quality finish that won't need several fixes. This set includes four individual brushes measuring 15mm, 18mm, 21mm, and 25mm. Suitable for use with water-based paints.
