This is a cover for a Takahashi Techo notebook. However, it should probably fit most standard A5-sized business notebooks (*^^*) It's made of thin fabric and feels light. I bought it as scrap fabric, so I don't know the exact type of fabric. I've added lots of pockets. Please remove the cover from your product and attach it to the notebook itself. The product itself is cool, but isn't it nice to spend time surrounded by cute things? ⸜(* ꒳ * )⸝ Why not try working hard while being soothed by cute things? There's still room for improvement, but I've made it in the shape I thought would be nice for a cover ( ¯꒳​¯ )ᐝ The pocket on the back cover side is deep enough to hold business cards. The photo shows the cards slightly raised. I'm also making them with other fabrics, so please take a look at my other works if you'd like ( •ᴗ• ) Add a little color to your everyday life. Why not add a little color to your ordinary day? #MaasansBookCover #MaasansHandmade #NotebookCover #BookCover #TakahashiTecho
