Keep the source.

Never invent the drop.
One checked price is one observation, not a trend. Undated snapshots never become price drops or target alerts.

Cotman Watercolors offer Winsor & Newton's renowned quality at an accessible price for students, beginners, and budget-conscious artists. Available in 8 ml and 21 ml tubes, the range features over 40 colors carefully selected for their tone, undertone, strength, and versatility in mixing.
Formulated with a blend of traditional and modern pigments—from natural earths to vibrant organic pigments—these colors allow for a variety of effects, from easy lifting to subtle washes to expressive, high-staining color. Most colors are transparent, with a smooth, consistent texture that makes them easy to work with, especially for those just starting out.
