How to use

Load the brush with a moderate amount of paint and remove excess on the palette or rim to avoid drips. For base coats and broad coverage, use the flat side and long strokes for even application. For washes and gradients, thin paint as required and use the flat edge to feather transitions. For straight lines and edges, hold the brush at a slight angle and use controlled, steady strokes. Clean the bristles after each session with water and mild soap appropriate for acrylic paints, reshape the tip while damp and store horizontally or bristle-up to preserve shape.

Usage recommendations

Use with water-based acrylics and model inks for best results; avoid prolonged exposure to strong solvents that can damage synthetic fibers. Rinse frequently during use when working with pigments or textured media to prevent build-up and maintain consistent performance.
