I bought this as a diary for the new year, and I was relieved to see that each page has a section to write the day of the week, making it suitable for use as a diary rather than just a memo or notebook ♡. ・It came with a star-shaped key, and there were two spare keys! They're small and easy to lose, but it's great to have an extra one. ・The cover is thick and very sturdy, which surprised me! Even if I accidentally drop it from my desk, the sides of the book are less likely to get damaged, which is helpful ꒰ ᐡᴗ͈ ·̫ ᴗ͈ ꒱♡. What could be better: ・There was a small scratch on the side of the book (the paper side), likely due to the pen's protrusion that was attached to it.
