Derwent Waterbrush Set — Push-Button Refillable 4-Piece Assorted Tips (2-10mm)

Derwent Push Button Waterbrush Assorted Set contains four refillable waterbrushes with push-button control and durable nylon tips for precise and versatile watercolour and water-soluble pencil work.

This set brings a portable, controlled water source to sketching, painting and mixed-media techniques. Each brush features a leak-proof barrel, a push-button that meters water flow, and resilient nylon fibres that retain their shape. The four-tip assortment ranges from a 2 mm fine point to a 10 mm chisel, covering detailed line work through broad washes. Designed for indoor studios or on-location work, the brushes are easy to refill and simple to clean after use.

How do these waterbrushes control water flow for different effects?

Each brush uses a push-button mechanism that releases water into the nylon tip when depressed, giving you immediate, tactile control over moisture levels. You can quickly switch from a dry, precise stroke to a saturated wash without changing tools.

• Push-button allows incremental water release for subtle gradients.
• Leak-proof design prevents drips during travel.
• Different tip sizes let you match flow to stroke width and pigment load.

Which tip sizes are included and what strokes do they make?

The pack contains four distinct tips: 2 mm fine, 3 mm medium, 4 mm large, and a 10 mm chisel tip. Together they cover delicate detailing, medium lines, broader washes and angled chisel strokes for edges or lettering.

• 2 mm fine tip — precise lines, small highlights and controlled details.
• 3 mm medium tip — outlines, short strokes and light washes.
• 4 mm large tip — fuller strokes and mid-sized wash areas.
• 10 mm chisel tip — broad washes, angled strokes and flat fills.

How do you refill and maintain the brushes to last longer?

Refilling is straightforward: unscrew the barrel, pour water in, and reattach. Cleaning requires running clear water through the tip while depressing the push button to flush pigment; the nylon fibres hold their point through regular care.

• Barrels are refillable and simple to open for hydration or cleaning.
• Flush tips with water after each session to avoid pigment build-up.
• Replace protective caps when not in use to preserve tip shape and prevent damage.

Who is this for? Artists, illustrators and hobbyists who work with water-soluble pencils, inks and paints will appreciate this set’s portability and versatility. It’s ideal for sketchbook artists who need a compact water source on location, students who want a reliable tool for mixed-media practice, and anyone seeking brush options that span fine details to broad washes without carrying a separate water container.
