One of our most popular lapboards from OptiMA® Graphics are the double sided graph boards in either a traditional 9" x 12" or a larger 11" x 17" size.

Individual student lap boards with a black, bold, X and Y axis printed on a light gray 3/4" x 3/4" grid pattern. Double-sided, non-magnetic lap boards with the X/Y graph and 3/4" grid on one side and a plain white, Melamine dry erase writing surface on the other side.

The X/Y graph and grid pattern are permanently printed onto the boards and covered with Opti-Rite® clear dry erase writing surface providing you with one of the best dry erase writing surfaces on the market.

Each unit is double sided, approximately 9" x 12" or 11" x 17". They are both 1/8" thick and come with bull-nosed edges and rounded corners for added safety and comfort. Normal lead-time is about 3-5 business days to ship from the factory in Massachusetts. School purchase orders accepted.

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.
