Pebeo Drawing Gum Marker Pen has an extra fine 0.7 mm nib for masking off detailed areas that you wish to remain white when painting with watercolours, inks or diluted gouache. The liquid frisket for watercolour & airbrush inside the marker is water soluble when wet and waterproof after drying.

This high precision Pebeo Drawing Gum Marker Pen is a great tool for applying masking fluid quickly, accurately and easily without ruining your paint brushes. The pen is single solution which replaces the drawing gum bottle, paint brush and water container in your kit.

The 0.7 mm plastic nib allows for clean, fine and well defined continuous applications when painting, drawing, writing or adding finishing touches, without clogging. Remove and clean the pen nib after use with warm water. Replacement tip included. The durable tip withstands repeated opening and won't break or splay.

It can be used on paper, cardboard, Bristol board, acetate, wood and other surfaces.

It contains a peel able rubber latex solution that is lightly tinted so that you can easily see where you have applied the drawing gum. Apply colour when the drawing gum is dry. Once the colours are completely dry just rub the slightly blue gum film with your finger or with an eraser to reveal the masked parts.

Store this masking fluid pen flat when not in use and preferably use within 12 months of opening.
