Raphael SoftAqua Synthetic Squirrel Watercolor Brush Quill 6 - Soft

In this review of the Raphael SoftAqua Synthetic Squirrel Watercolor Brush, Quill, 6, the bottom line is simple: this brush is for watercolorists who want a soft, highly absorbent quill that holds lots of water and pigment for longer strokes and detailed work. The reviewer found the brush shines when you need excellent water retention and a fine point for detail; its synthetic, wavy fibers mimic natural squirrel hair while offering improved paint capacity. For artists who value a soft tip that keeps shape and delivers consistent color flow, this brush stands out.

Key Features

• Soft synthetic fibers: The brush uses 100% synthetic hair engineered to feel soft and responsive like squirrel, helping with controlled washes and delicate marks.
• High water retention: Wavy undulating fibers create internal spaces that trap more water molecules, allowing longer continuous strokes without frequent reloading.
• Twice the color hold: The wavy fiber technology holds up to twice as much pigment compared with straighter synthetic bristles, so broader washes lay down more color in one pass.
• Fine point and shape retention: The quill form and fiber shape let the brush come to an accurate tip for fine detail while keeping its shape through repeated use.
• Versatile stroke range: The brush delivers varying brush strokes from broad washes to hairlines, making it suitable for works of art of any size.

Who It's For

This brush is best for watercolor painters who need reliable water and pigment carrying capacity, especially illustrators and plein air painters who prefer fewer dips into the palette. The soft, quill-style head makes it particularly good for artists focused on smooth gradients, wet-in-wet blends, and intricate details where a fine tip matters.

Artists who prefer very large wash brushes or a firmer, springier synthetic may want to look elsewhere, as this quill leans toward softness and maximum water retention rather than rigid snap. It is also less suitable if you want a heavily textured brushstroke or very abrasive surface work.

Pros & Cons

Pros

• Excellent water retention that enables long, uninterrupted strokes and richer washes.
• Soft, squirrel-like feel from 100% synthetic fibers that still reach a precise point for detail work.
• Strong shape retention so the quill keeps a defined tip over multiple painting sessions.
• Capacity to hold twice the color compared with straighter synthetics, reducing palette reloads.

Cons

• Size impressions are mixed among users, so the physical dimensions of a Quill 6 may not match every painter's expectation.
• Very soft feel may not satisfy those looking for a springy, resilient brush for textured marks.
