OptiMA® 9" x 12" double-sided, handheld line graph boards with a printed graph on one side of the board and a white Melamine dry erase writing surface on the reverse side. The grid pattern has bold axis lines with a ghosted gray grid pattern with a slightly bolder line every 5 rows and every 5 columns. These boards are great for teaching line graphs and bar charts. The boards are 1/8" thick. The boards have rounded bullnose edges for the comfort and safety of the user. Normal lead-time is about 3-5 working days to ship from the factory in Massachusetts. We accept school purchase orders.

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