Thank you for viewing. A4 board cover, 2-hole type, 306 x 217mm Set of 5 packs Total 200 sheets Each pack contains 20 sheets with fold lines and 20 sheets without fold lines, totaling 40 sheets per 20 sets. Although new and unused, it has been stored at home. 3 packs are unopened. 2 packs have been opened with tape, but the contents have not been taken out, so they are unused. Board covers are a type of paper, thick cardboard used to bind documents. The paper itself has two holes, and you can use it by binding it with string (string is not included). In addition to being used as a cover for storing documents, due to its durability and resistance to bending, it can also be used when sending documents that must not be bent, as POPs for stores, or as drawing paper or craft paper for children. I would like to give it to someone who can use it, as I will not be using it. Thank you for your understanding.
