we were actually too stupid to realize that there is a protective film on the board it! We bought it as a spare table for the kids, extra blades and a wiper to. The kids have unpacked the board and equal described. The shock was great when the pins did not go away! No matter what we have taken, the first wiper, then water, then a sponge, then always hardness cleaner, it always remained despite great Kraftanstrenung color pigment on the board. I was totally disappointed and thought, what do you expect otherwise for the money, wanted to give a bad review and buy a more expensive board, because the idea itself is so good!
Then came the Enlightenment, on the board is a sheet on it! The is so taut that you barely saw it. So slide off and carefully made a small stroke on it, over it with the extinguisher and the line was gone!
So we shall get 5 stars, the board may be all a whiteboard can have!
