What do I do with my paperblank memento pouch?
(Please don't mind the tear from the stupidly placed sticker, I'm already miserable enough about it as is)
On the website they suggested putting cards and loose papers in there but I don't think I'd have many of those as I plan to write the plot for my manga/s in the notebook but I still wanna utilise the book fully including this.
(Also if anyone curious I got the violet fairy one ^^)
