This is thick paper (cardboard). The front is glossy white, and the back is gray. The size is A4 (21cm x 29.7cm). The thickness is about 0.8mm. The quantity is 240 sheets (30 sheets x 8 bundles). It is also thick and I think it is easy to use. How about using it not only as thick paper, but also 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 rise in paper prices. #papergoods #specialtypaper #handmade #handmadematerials #handmadematerials #papercraft #papercraftmaterials #papercraftmaterials #craftpunch #diecut #paper #paper #cardboard #whitecardboard #whitecardboard #chipboard #chipboardpaper #thickpaper #craft #cardboard #backingboard #bookbinding #reinforcement #corematerial #protection #packaging #packingmaterials #cardprotection #bookpackaging #A4
