This is thick paper (cardboard). The front is a matte white with no gloss, and the back is gray. The size is A5 size (21cm x 14.8cm). The thickness is about 1.0mm. The number of sheets is 50. It is also thick and I think it is easy to use. As well as thick paper, how about using it for handmade crafts, as a backing board or material for creating works? ※ Please note that the wrapping paper used to wrap the product is reused due to the recent price increase of paper. #paper #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 board #bookbinding #reinforcement #core material #photo protection #photo packaging #book packaging #A5
