Langton Watercolour Bound Pad A2 (420 X 594mm) This Daler-Rowney Langton Watercolour Pad Cold Pressed has been popular with watercolour artists for years, and once you try it you’ll soon see why. Langton paper is colour-stable, mould-made and acid-free, to prevent deterioration over time. This cold-pressed, or "Not", variety is the most popular of watercolour papers, with a medium texture that makes it suitable for most effects and types of watercolour painting. Daler-Rowney Langton Watercolour Pads are gummed, making it easy to remove the sheets, and each contains 12 sheets of 300gsm paper. Cold Pressed, 16.5 x 23 inches.
