Professional synthetic watercolour brush that mimics natural squirrel hair
The SoftAqua 805 uses patented synthetic fibres developed by Raphaël's R&D department. Unlike standard synthetic brushes that can feel stiff or hold less water, these fibres have a wavy structure that creates microscopic spaces — essentially tiny reservoirs that trap water and pigment.
💧 Key advantage: The fibres hold up to twice as much fluid as standard synthetic bristles, giving you longer strokes without needing to reload your brush constantly.
The goal was simple: replicate the softness, spring, and water capacity of natural Petit Gris squirrel hair, but without using animal fur. If you've worked with natural squirrel brushes before, you'll recognize the familiar feel — that gentle give and excellent water retention.
The Pointed Mop (also called Quill) shape looks like a light bulb — a full belly tapering to a fine point. This gives you:
| Size | Diameter | Hair Length | Best For |
|---|---|---|---|
| 3/0 | 5mm | 19mm | Fine details, delicate lines, botanical illustrations |
| 0 | 7mm | 23mm | Small washes, lettering, miniature work |
| 2 | 9mm | 28mm | General purpose, medium washes, versatile everyday use |
| 4 | 11mm | 34mm | Larger surfaces, portrait work, landscape elements |
| 6 | 14mm | 38mm | Big backgrounds, sky washes, loose painting |
| 8 | 17mm | 42mm | Full-page washes, large format work, atmospheric effects |
🖌️ Handle design: Short black matte handle provides excellent balance and control. The shorter length keeps your hand closer to the paper, giving you better precision — especially useful for detailed watercolour work where you need fine control.
This is where the brush really shines. Use it for:
Works brilliantly with liquid inks:
Stays soft even with opaque paint:
Even application of coloured films:
For lighter acrylic techniques:
Heavy-bodied acrylics or oils straight from the tube. The soft bristles are meant for watery media. If you're working with thick, undiluted acrylics, you'd be better off with something like the Raphaël Kaërell series which has stiffer synthetic fibres.
Synthetic brushes last longer than natural hair if you care for them properly. Here's what actually matters:
Keep your brushes in a dry, well-ventilated spot. A brush roll or standing upright in a jar works fine. Just make sure they're completely dry first to avoid mildew.
No — the SoftAqua fibres are specifically engineered to snap back to shape after each stroke. You won't get the splaying that happens with cheaper synthetics. As long as you're not scrubbing hard surfaces or using it with thick paint, the tip should stay sharp for years.
Yes, but only if you dilute them with water. Think thin glazes or watercolour-style acrylics. For thick, straight-from-the-tube acrylics, you'll want something with stiffer bristles like the Raphaël Kaërell series — those are built for heavy-bodied paint.
The water capacity is comparable, and the softness is very close. The main difference: synthetic is more durable. Natural squirrel hair is delicate and can shed over time. With the SoftAqua, you get similar performance but with better longevity and no risk of bristles falling out.
If you're painting on standard watercolour paper (A4 or smaller), size 2 or 4 is a solid all-rounder. Size 2 handles details and medium washes. Size 4 gives you more coverage for larger areas while still being controllable. You can always add smaller or larger sizes later.
Absolutely. The brush is very forgiving — it holds plenty of water (so fewer trips back to your palette), maintains its shape (so you're not fighting with splayed bristles), and the soft fibres won't damage paper. It's professional-grade quality that's easy to use, which is ideal when you're learning.
