Thank you for viewing. Please read my profile. ⚠️This sale is for the M5 (Micro 5) size system notebook cover only. (=^▽^) Made from flavorful, firm, and sturdy genuine cowhide leather. It's hard like saddle leather, but it's not saddle leather. Since it's vegetable-tanned leather, you can enjoy its aging process. As you use it, the wax will naturally wear off, making the black even deeper and developing a beautiful sheen! It's the same leather as the coin case I recently listed. (>◡<) The flesh side and edges have been carefully finished. ⚠️Handmade. I may incorporate the natural character of vegetable-tanned leather, such as scratches, scuffs, wrinkles, and brand marks, into my creations. However, I try to cut from the cleanest parts possible. But if I want to utilize those features, I will use them. I would appreciate it if you understand that this is the nature of vegetable-tanned leather. （╹◡╹）♡ If you have any questions, please comment. ☆*:.。. o(≧▽≦)o .。.:*☆ ⚫︎Material: Genuine cowhide leather, wax leather ⚫︎Color: Black ⚫︎Thread: Black polyester bond thread ⚫︎Size: Approx. 13 x 10.5 cm (Please allow for slight variations.) ⚫︎Weight: Approx. 108g ⚫︎Binder mechanism: Nickel ⚫︎Assembly screws: Brass silver ⚫︎Includes pen holder. ⚫︎2 free pockets. ○Reference refill size: 105 x 62mm, 5 holes ○The 3-color ballpoint pen is approximately 15cm long. （╹◡╹） →→Please be sure to read the following. ⚠️Caution I own cats, so please refrain from purchasing if you have allergies or are sensitive.
