This is a set of 5. ・Cover and back cover: Blue ・Size: A7 ・Horizontal writing ・6.5mm ruled lines Have you ever left a notepad in your clothes pocket and washed it, only to have the notepad become a mess and ruin all your notes? This ring notepad uses water-repellent paper, so it's okay even if you wash it! I myself use this notepad, and even after washing it: ・The part written with a mechanical pencil will fade slightly ・The part written with a ballpoint pen will bleed a little But it's still perfectly readable, and the paper hasn't dissolved. Currently, it's almost impossible to find in stores, making it a hard-to-find item.
