Hello! Thank you for looking. This is a book cover made using Minä Perhonen fabric. (Back side: 50% cotton & 50% linen) The back side is also fabric, so if it gets dirty, you can remove the cover and wash it♡ Size: Approximately 23cm x 15.2cm It's a paperback size. It can also be used as an A6 size notebook cover ^ - ^ I make them carefully, but they are handmade by an amateur who loves crafts. There may be some slight misalignments or distortions. I would be happy if those who understand handmade items would purchase them. Instant purchase is OK! You don't need to comment! If you have any questions, feel free to comment ( ◠‿◠ )
