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 the 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
