Trekell Spectrum Long Handle Artist Brushes | Versatile Synthetic Bristles Trekell Spectrum brushes are designed for artists who want the look and feel of natural hair with the durability and consistency of a high-quality synthetic. Like all Trekell premium synthetic brushes, Spectrum features a blend of varying filament diameters with carefully tapered tips that more closely mimic the performance of natural brush hair. This advanced filament construction provides excellent paint pickup, smooth paint flow, and responsive handling that cheaper synthetic brushes with uniform, blunt-cut filaments simply can't match. What sets Spectrum apart is its proprietary smooth synthetic filament. Unlike many synthetic brushes, Spectrum filaments have an exceptionally smooth surface with virtually no microscopic divots. This allows paint to release evenly from the brush, minimizing visible brush marks while producing exceptionally smooth blends, soft transitions, and refined finishes across a wide variety of painting techniques. Each brush is made with Trekell's Thermyx™ filament. During manufacturing, the bristles are heat-set to create built-in shape memory that helps the brush maintain its shape, edge, and performance over time. If the bristles begin to lose their form, a quick dip in simmering water can help restore them closer to their original shape. For best results, reshape the bristles while warm and allow them to dry in place. Applying Trekell Brush Restorer while the bristles dry will help the bristles hold their shape longer between painting sessions. The 10-inch long handle provides excellent balance and control, allowing you to move comfortably between precise brushwork and broad, expressive strokes.
