Double Sided Grid Lapboards 9" x 12". The grid pattern is a light gray 3/4" x 3/4" grid pattern. The grid is just dark enough for the user to see but not so dark that it's not easy to work with. The grid is 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 cheap screen print that chips off or wears away. This grid pattern will never fade away.  Tip: It is not recommended to clean these boards with anything containing ammonia which is found in most glass cleaners.
It is not recommended to use damp / wet erase markers with these boards. If it is necessary to use wet erase markers, erase clean with a damp cloth within 24 hours.
