Illumigraph Pens offer a brighter, fluorescent range of colours and are designed for internal use. They will glow up under UV light. They wipe off any non-porous surface easily with a damp cloth (same ink-type as the Wet-Wipe pens).
To get a clean finish, we recommend using "Mr Muscle Glass & Window Cleaner" or our "Zig Chalkboard Cleaner".
Ideal for use on: Chalkboards, Whiteboards, Glass, Plastic, Mirror, Metal, Slate and many more!
Safe and suitable for children. Water-based Ink, Non Toxic & Xylene Free!
Please note: MDF boards which are painted with Chalkboard Paint can sometimes absorb the ink. To avoid staining your boards, we recommend you use at least 3 or 4 coats of paint to seal the board. That way the ink is less likely to be absorbed.
