SplinkTeach - 2m x 60cm Dry Wipe Removable Whiteboard Vinyl Wall Sticker Office Home +3 Marker

If you lack of space to get a proper board and you need something on the go, this whiteboard will do the job.I have currently installed it to a wooden painted door. Since I was a bit skeptical about the sticky glue not removing any part of the paint from the door, I gave it more than a test and every time I removed the sticky board from the door, it never scratched or ruined the paint.You can cut it and shape it as you like to make it fit everywhere you need and it works just as a regular whiteboard.It can be easily cleaned with kitchen paper or a dry cloth.The only real problem is that if you don't know how to stick the adhesive in the proper way, you will get plenty of bubbles, so pay a lot of attention while doing it.Considering the price and the quality, definitely a good product I would advice.
