The Pebeo MAGIC! Drawing Gum Marker for Children is a latex-free masking fluid formula in a children's size marker for easy handling. Its 4 mm round tip is ideal for drawing and adding details. Easy to use, it is applied to mask areas prior to applying colors. Once the application is dry, colors are applied and left to dry. The Drawing Gum can then be removed, either by rubbing with fingers or with an eraser, to reveal color-free lines and details.
