I bought a lot of these because I liked them, but I ended up buying too many, so I'm selling them. These are spiral notebooks with 80 sheets, featuring 5mm grid lines. Set of 3 notebooks. These have been stored at home, so there may be some scratches or imperfections on the covers. I don't think it will affect the use, but please be aware of this. - Model: N246ES - Size: 252x179mm - Number of pages: 80 sheets - Ruled lines: 5mm squared - Type: Spiral notebook Thank you for looking.
