The eraser comprises: a main body which has a storage part to store water inside, an injection part on a side to inject water into the storage part, and multiple discharge holes at the bottom to discharge the water from the storage part; a pad which can be attached/detached to/from the bottom side of the main body; and control means which is installed inside the main body and which opens or closes the entrance of the discharging holes to supply the water to the pad under control. |
