Thank you for viewing! This is a handmade book cover for a paperback book. Interfacing is used to give it firmness. It can be adjusted to fit the thickness of the book. Size: Approximately 16cm (height) x 31cm (width) ◈ The paperback book is for photography purposes only and is not included. ◈ The inner fabric is basically unbleached cotton fabric (this is not a stain). ◈ It's difficult to capture the colors accurately in photos. Please understand that there may be differences from the actual product. This is a handmade item by an amateur. There may be some wrinkles, distortions, and stitching corrections. Please understand this before purchasing. #SKBookCover
