I've used these; perhaps not this exact brand but the same generic product. Sheets of thin white plastic that adhere using static to walls and other surfaces.

They work pretty well; you have to take care not to get crinkles or wrinkles in the sheet of course, and not be too decisive with the eraser or you'll pull the sheet around on the wall.

The major problem these can have is that there is no border; the sheet is very thin and its easy to slip up and draw outside.

I've used them as well. To me they are TOO thin (though I understand why). They're too small, take on too much of the substrate's texture, and suffer the problems "unwind" mentioned.

Would love to try that paint, but I have a (perhaps neurologically unsound) love for really, really big whiteboards. Me trying to compensate for something, perhaps...?

I fix that by drawing a border (with a red marker -- hard to miss).

At last a purpose for those permanent markers that people use accidentally on a whiteboard now and then :-)

Now that is a cool hack.

I have to say, this looks more attractive to me than the paint from the other thread.

I wonder how effective the static remains over time. Does anyone have any experience with this? Otherwise it does look like a pretty good product.

I've used them before when teaching; not bad, but the surrounding walls may become filthy if your erasers are not spotless.

It looks like a gigantic roll of cling-wrap/cling-film. How it is reusable (effectively) is the vital question.

these have been around for 10+ years...
