Fill in water resistant blackboard for civil engineering work

Because it erases frequently, it is sometimes inconvenient for it to be difficult to erase without water. However, it is very good if you use it for characters that you do not want to disappear. If you do not forget water and towel, you can use it enough for waterproof blackboard for construction. The price is reasonable, I think that it is a good product because the pen tip will not be crushed.
