Check out the broad selection of wet and dry erase markers at Grainger when your supply runs low. Primarily used for teaching and presenting, a dry erase marker can be left cap-off for long periods of time, drying them out quickly. It can be frustrating to pick up a marker and try to use it, only to find it has already dried up. Check your supply often and replenish with wet and dry erase markers from Grainger.
