Materials: Italian leather (Margot) Hard clear sheet Hardware: Mini 6 binder hardware, gold Size: M6 Color: Naturale (Natural) Specifications: Slip-in type *Refills are not included. Thank you for viewing. This is an M6 system notebook made of hard clear material and Italian leather. A Rollbahn M size fits just barely. This time, I made it in a warm color series. Next time (though it will be a little while), I plan to release a cool color series of cobalt blue, turquoise blue, peppermint green, and taupe. It can also be used as a sticker notebook or an "oshi-katsu" (supporting your favorite idol/character) notebook. The leather part uses Margot leather. Margot leather is characterized by a rough texture like Japanese paper, but the color deepens and the luster increases the more you use it. The clear part uses the same material as a hard card case. Since the leather is a natural material, there may be small scratches or color unevenness. Also, the color may look slightly different from the actual product depending on the device you are viewing. Please understand that this is a handmade item before purchasing. #SystemNotebook #ItalianLeather #ClearBinder #OshiNotebook #OshiColor #StickerNotebook #MargotLeather #Rollbahn
