Trekell Onyx Brushes

Our Onyx Synthetic Squirrel brushes are designed for artists who want the softness and absorbency of natural squirrel hair with the reliability and durability of a high-quality synthetic.

Like all Trekell premium synthetic brushes, Onyx 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 exceptional paint pickup, smooth paint flow, and responsive handling that cheaper synthetic brushes with uniform, blunt-cut filaments simply can't match.

What sets Onyx apart is its ultra-soft synthetic filament, engineered to replicate the feel, absorbency, and fluid paint release of natural squirrel hair. The highly absorbent filaments hold generous amounts of water, paint, and medium, allowing you to create smooth washes, effortless blends, soft edges, and fluid transitions with minimal reloading. Unlike natural squirrel hair brushes, Onyx delivers consistent performance without shedding while maintaining the softness and flow artists expect from professional wash brushes.

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 6-inch short handle provides excellent control and comfort, making these brushes perfect for detailed work, delicate applications, and controlled washes.
