The combination grid and work space lap boards come in two styles; with a ghost grid or with an X/Y grid. For both styles, the squares are approximately 1/2" x 1/2" and a light gray color that is dark enough to be visible but light enough to work with.

The grids are permanently printed onto the lap boards and then they are covered with one of the best dry erase writing surfaces in the world. This isn't a cheaper screen print that chips off or wears away. These grid patterns will never fade away.

Tip: It is not recommended to clean these boards with anything containing ammonia which is found in most glass cleaners.
