This is thick paper (cardboard). The front is a matte white without gloss, and the back is gray. The size is A5 (21.0cm x 14.8cm). The thickness is about 1.6mm, making it a fairly thick type. The number of sheets is 36. 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. #papergoods #specialtypaper #handmade #handmadematerials #handmadematerials #papercraft #papercraftmaterials #papercraftmaterials #craftpunch #diecut #paper #paper #cardboard #whitecardboard #whitecardboard #chipboard #chipboardpaper #Pokemoncardpackaging #thickpaper #craft #cardboard #backingpaper #bookbinding #reinforcement #corematerial #photoprotection #photopackaging #bookpackaging #A5
