This item uses fabric from Nijineko Honpo☆ It comes with a bookmark and an elastic band to keep the book closed. Please refrain from purchasing if you are looking for perfection or are overly concerned with details, as this is a handmade item. It is for standard-sized paperback books (excluding Hayakawa's Tall size). Interfacing is used. I started making these because I love to read and wanted to prevent my books from opening up or getting dirty in my bag☆ I often borrow books from others, and having one of these is convenient for keeping them clean^_^ I hope it can be useful to someone（╹◡╹）♡ ※ ¥100 off from the second item for multiple purchases☆ ※ If you purchase multiple items, please use the combined purchase feature or comment on each item（╹◡╹）♡ ※ Please note that the person who presses the purchase button first will be given priority, even if there are comments. ※ Please refrain from purchasing if the item is marked as "reserved" for someone else^_^
