1. Detailed corners/edges – Flexible rounded head reaches narrow spaces (e.g., wall corners, window sills, carved details).

2. Smooth surfaces – Tightly tapered bristles adhere to flat finishes (e.g., latex paint, tiles), controlling paint flow for even, streak-free results.

3. Small-area thin coats – Ideal for spot touch-ups or low-viscosity paints (e.g., clear varnish, water-based), preventing drips with precise application.
