The Propic blender is a tool for modulating and shading and is applied on top of a drawing made with Propic markers.
Propic is a line of non-washable alcoholic markers filled with ink based on a special alcohol solution. They are especially useful for writing and drawing on paper, but are also ideal for wood or plastic, so can be successfully used in restoration.
Propic markers are not only hydrophobic but are also resistant to smudging. Tones can be very easily modulated, forming smooth transitions with the use of a colourless blender. Each Propic marker has two tips: one thick and truncated for backgrounds or larger areas, and the other thin and conical for more precise work.
