This is a handmade book cover with a slight imperfection. *Please check the condition in the images. The size is for a Japanese "shinsho" book (103mm wide x 182mm long), and when unfolded, it's approximately 19cm wide and 31cm long. Since it's handmade, there may be slight variations, so please understand. *Please note that there are several types of "shinsho" size books. Please also see my profile. Shipping will be via regular mail (定形外郵便). Please note that delivery may take longer as the post office is closed on Saturdays, Sundays, and holidays, even if the item has been shipped. Thank you for your understanding.
