This is a handmade book cover, carefully sewn with a sewing machine. It was made to fit A6 size books (14.8cm x 10.5cm). Product size (outer dimensions): Approximately 30cm x Approximately 15cm Both the outer and lining fabrics are made of cloth, and an interlining is used inside, providing moderate thickness and stability. With a lining, it gently protects your book. We make each one with care, hoping to make your reading time a little more enjoyable. Because it is a handmade item, there may be slight individual differences, but we hope you will enjoy that aspect as part of its character. Thank you for looking. #handmade #stationery
