Da Vinci Watercolor Series Petit Gris Pur Brush Set 5358-2

The 5358-2 set pairs traditional quill brushes with the Pur hair blend, focusing on mop and wash techniques with generous water capacity. Hand-shaped bristles and a large reservoir facilitate broad, even washes across the paper, enabling artists to cover large areas efficiently while maintaining control across strokes.
Da Vinci Watercolor Series 418 Petit Gris Pur, Size 2/0

The 2/0 variant maintains the same high-quality Russian blue squirrel hair, delivering exceptional water-holding capacity with precise control. Designed for fine-tuned mop work, it balances a broad reservoir with a tapered tip, enabling smooth transitions and clean washes without overloading the paper.
Da Vinci Watercolor Series 418 Petit Gris Pur, Size 4

This larger 4-size brush keeps the same water-holding efficiency while offering a broader footprint for wide, even washes. The quill’s curvature supports steady, continuous strokes, and the reservoir reduces reloading frequency, benefiting larger watercolor surfaces and gradient work.

Buying Guide: Da Vinci Mop Brush Buyer’s Considerations
- Hair type and water retention: Russian blue squirrel hair is prized for high water absorption and smooth release, ideal for large washes. Consider the balance between water capacity and tip control for your typical project size.
- Brush size variety: For mop and wash work, larger sizes provide broad coverage, while smaller sizes help with controlled edges. A mix of sizes supports both broad gradients and fine details.
- Shape and point: Pur Petit Gris brushes offer a generous reservoir with a slightly rounded point, allowing broad strokes with the possibility of refined lines when needed. The quill shape affects stroke consistency across the paper.
- Set vs. single brush: Sets provide a range of sizes and quick-start versatility, while single brushes allow focused investments in your preferred sizes. Gift box sets also offer convenient storage and presentation.
- Maintenance and longevity: High-quality natural hair brushes require careful cleaning and reshaping after use. Drying flat with the bristles facing down helps maintain the tip and reservoir integrity over time.
- Price-to-performance: While Da Vinci mop brushes can be an upfront investment, their water-holding capability and durability can translate into faster coverage and smoother gradients for larger works.
- Compatibility with mediums: While designed for watercolors, some brushes with synthetic fibers (like the Casaneo line) offer similar performance but different maintenance profiles. Consider your preferred texture and color absorption.
