The present invention relates to a water blackboard eraser and, more specifically, to a water blackboard eraser capable of removing residual water on a blackboard by mounting a wiper on the water blackboard eraser. Residual water is removed by the wiper after a cloth of the water blackboard eraser is scrubbed by using water in the blackboard, thereby a scrubbed part can be immediately used and flow down of the water can be prevented. Therefore, the disconnection of the lesson does not occur and a mark flowing the water does not leave. |
