You can use either Dry Erase or Wet Erase markers.
However, we have found that some dry erase markers may stain the board. So we recommend using ONLY the
Expo Vis-a-Vis Pen Wet Erase. They are use with overhead projectors. It wipes off easily with a damp paper towel
or damp cloth. You can order these directly from us. See the Clap Pen Below.
Besides writing in the name of the Production, Directory, Camera and the Date. You can always use removable vinyl letters and numbers. The ones
we have used are made by Chartpak and are called Pickett Design Vinyl Numbers/Letters Stickers, 3/4", Black. You can get them in other sized, but
the 3/4 inch ones fit the best.
