Dr Ph Martins Bleed Proof White is an opaque watercolour that can be used to cover dye-based colours, markers and designer colours. It is a brilliant white with excellent covering power. This product should be used for covering only - not mixing with colour. It can be applied with a brush or dip pen, and can be thinned with water.
Bleed Proof White comes in a 30ml (1 oz) glass jar.
