This is thick paper (kraft cardboard). Both sides are the same material, a kraft-textured cardboard that is slightly more yellow than the image. The size is A4 (21.0cm x 29.7cm). The thickness is about 1.1mm, making it a thick type. The number of sheets is 25. It is quite thick and I think it will be easy to use. As well as thick paper, how about using it for handmade crafts, artwork backing, or materials? ※ 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 #HandmadeSupplies #PaperCraft #PaperCraftMaterials #PaperCraftSupplies #CraftPunch #DieCut #Paper #Cardboard #WhiteCardboard #WhitePaperboard #Chipboard #ChipboardPaper #PokemonCardPackaging #ThickPaper #Crafts #Paperboard #BackingBoard #Bookbinding #Reinforcement #CoreMaterial #PhotoProtection #PhotoPackaging #BookPackaging #A4
