The Squirrel and the Red Sable are extremely fine and soft and they fold under the slightest pressure from the hand, fanning out, giving a broad stroke and returning to their initial positions whilst retaining a perfect point.
Using the Isabey Squirrel, which is a real water reservoir, allows you to place the subject into its context.
The expressiveness of the Sable brushes means that they take more colour, less water and offer greater relief and intensity.
