Winsor & Newton Professional Watercolour Blocks - 300gsm - 20 Sheets

Winsor & Newton Professional Watercolour Paper Sheets are made with 100% cotton on a traditional cylinder mould, ensuring a high-quality and archival surface.

The cotton fibres are internally and externally sized for optimal absorbency and strength, preventing the paper from warping, even when washed with water or multiple layers of paint. The paper is acid-free and free from any optical brighteners.

The cotton in the paper gives a natural whiteness that does not yellow or degrade over time. Ideal for use with all watercolour paints, gouache, ink and watercolour pencils or markers.
