Holbein Watercolour Masking Ink Pen (25ml)

Holbein Masking Ink allows you to protect highlight areas of your work when painting with watercolours. 
Allow your masking ink to dry before applying watercolour. To remove dried masking fluid, use a soft eraser or a rubber pick up.

The Holbein Masking Ink Pen is perfect for smaller areas, drawing fine lines or detailed expressions.
