This item was inherited from a company that my family closed. I'm not sure how old it is. The seal has some dirt and creases, so it might have been used, and there may be fewer than 20 sheets. If you wish, I can open it and count the sheets after purchase (please let me know immediately after purchasing). If there aren't enough, you can cancel the transaction. It will be packaged with a piece of cardboard and placed directly into an outer bag. ✳️Please read my profile before commenting, requesting a price reduction, or making a purchase. Protective Film Pop
