We've had these set out since purchase(2 weeks ago) separated from one another and flipped daily. The smell is still intense enough I can smell it at the doorway 10 feet away. I have never experienced a product with such a bad off-gassing problem. I would expect a warning or tip on how to lessen this issue on the FAQ page as well as included with the product. Hopefully these will actually be usable in time for the convention I purchased them for.
Aside from the off-gassing issue these seem to be sturdy pages and work well when tested with pins. Plan for multiple weeks of sitting out before any event use.
