This is thick paper (cardboard). The front is glossy white, and the back is gray. The size is A5 (21cm x 14.8cm). The thickness is about 0.5mm. The number of sheets is 96. It is thick and I think it is easy to use. How about using it not only as thick paper, but also as backing paper or materials for handmade crafts and artwork? *Please note that the wrapping paper used to package the product is reused due to the recent rise in paper prices. #papergoods #specialtypaper #handmade #handmadematerials #handmadematerial #papercraft #papercraftmaterials #papercraftmaterials #craftpunch #diecut #paper #paper #cardboard #whitecardboard #whitepaperboard #chipboard #chipboardpaper #thickpaper #craft #paperboard #backingpaper #bookbinding #reinforcement #corematerial #protection #bookpackaging #magazineprotection #magazinepackaging #cardprotection #A5
