I have a variety of items that I've had in storage for a long time. The outer packaging shows signs of aging, but the paper itself is clean. I hope someone can use these without concern. ● Canon Double-Sided Matte Business Card Paper Unopened, but I opened it to check the contents. 99 sheets + 1 sheet with yellowing near the tape residue. I've included the yellowed sheet for test printing. I'll put it on top. * The box may be folded for shipping. ● Kokuyo Inkjet Printer Paper Photo Paper High Gloss Postcard Size 14 sheets ● Fujifilm Gashis Photo Finish Value Glossy Normal 22 sheets Thank you for looking.
