I purchased this item and stored it on a bookshelf with the outer packaging (film) still on. There is no yellowing or folding. There are some scratches on the outer packaging, but the item itself is not damaged. I bought this intending to use it for pamphlets, etc., but I didn't end up using it, so I'm putting it up for sale. Please understand that this item has been stored by a private individual, and purchase accordingly. Thank you.
