This is thick paper (cardboard). The front is a matte white with no gloss, and the back is gray. The size is A5 (21cm x 14.8cm). The thickness is about 1.0mm. The number of sheets is 60. It is also thick 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 #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 #A5
