This book cover comes with a bookmark and an elastic band to keep it closed. Please refrain from purchasing if you are a perfectionist or overly concerned about minor details, as this is a handmade item. It is designed 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 spreading open or getting dirty in my bag☆ I often borrow books from others, and having one of these is also convenient for keeping them clean^_^ I hope someone finds this useful (╹◡╹)♡ ☆Depending on the circumstances, the shipping method may be changed from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin. If you prefer Yu-Yu for convenience store pickup, please leave a comment^_^ ※¥100 off for each additional item purchased. ※If purchasing multiple items, please use the bundle feature or leave a comment on each item (╹◡╹)♡ ※Please note that the first person to press the purchase button will be given priority, even if there are comments. ※Please refrain from purchasing if the item is marked as "reserved" for someone else^_^
