Sorry to dig this up,but I'm looking for info on these easels too. I've got a pretty good easel for 11x14 and full bleed (or near enough to) 14x17 paper. I don't want to assemble something complicated and hope this magnetic easel is pre-packaged goodness.

I know how nice normal easels are, but I'll rarely be making 16x20 prints.

My question, fiber paper that may curl a little, the magnets are probably pretty strong, but do the corners hold the paper sufficiently flat?
