A5 size cover made of pigskin, pink beige. This leather is about 1mm thick and lightweight. (^^) I think it's leather that will develop character the more you use it. The cover fits notebooks and planners that are 4-8mm thick. The leather is somewhat wild, with some dark areas and wrinkles. Therefore, although unused, there are some minor scratches and stains. Thank you for your understanding. m(__)m It has two pen holders. Make your usual notebook or planner special... (*^^*) How about it?
