This is thick paper (cardboard). The front is a matte white without gloss, and the back is gray. The size is 19.5cm x 14.8cm. The thickness is about 1.6mm, making it a fairly thick type. The number of sheets is 24. It is also sturdy and I think it is easy to use. How about using it not only as thick paper, but also as backing paper or material for handmade crafts and artwork? *Please note that the wrapping paper used to wrap the product is reused due to the recent price increase of paper. #paper goods #specialty paper #handmade #handmade materials #handmade supplies #papercraft #papercraft materials #papercraft supplies #craft punch #die cut #paper #paper #cardboard #white cardboard #white paperboard #chipboard #chipboard paper #Pokemon card packaging #thick paper #craft #paperboard #backing paper #bookbinding #reinforcement #core material #photo protection #photo packaging #book packaging
