A4 size, 0.18mm thick colored paper for laser, inkjet, and copy, pack of 4 sheets. I used this when making bookmarks. It was good because it was thick and sturdy, and photos came out beautifully. Would this be good for anyone looking for paper for test prints, etc.? - Brand: Nagatoya - Model Name: A4, 4 sheets - Size: A4 - Thickness: 0.18mm - Use: For laser, inkjet, and copy Thank you for looking.
