This is thick paper (cardboard). It's a rare type of thick paper with a matte white finish on both sides. The size is 14.5cm x 12.7cm. The thickness is about 0.9mm. There are 60 sheets. It's quite thick and I think it's easy to use. Besides being used as thick paper, how about using it for handmade crafts, artwork backing, or materials? *Please note that the wrapping paper used to package the product is reused due to the recent rise in paper prices.
