Yufuu-sama, Book Cover Order Rabbit Cage Pattern Bunko book size. Approximately 15.5cm x 29.5cm. Thickness is adjustable. Adhesive interfacing is applied to the surface. The bookmark is a little longer. You can cut it to your preferred length. This is a handmade item by an amateur. There may be some distortions or double stitching due to the sewing machine. I make each one carefully, but I appreciate your understanding of handmade products.
