Write and draw in straight lines!
The gridded version of Magic Whiteboard is specifically designed to retain ink better than the plain version, making it ideal if you want to keep your work for use at a later date. These reusable sheets can be folded or rolled and your work will not rub out! Ink becomes more permanent over time - after 1 - 2 days you will need a damp cloth or whiteboard remover.
Completely erasable, resuable and recyclable, each roll contains 25 A1 (60x80cm) sheets of Magic Gridboard that stick to any hard flat surface using static.
