Holbein Vanishing Paper- single sheet_
This unique paper from Holbein is also known as brush-up paper.
It is a great surface that enables artists and students alike to practice different brush strokes using various brush shapes. Simply wet a brush such as a watercolour brush and run it across the paper surface to create an image. The image remains visible for approximately ten minutes after which it disappears enabling the sheet to be used again and again. For use with water only.
