This is a handmade leather pen holder refill for Micro 5 (M5) size notebooks. The base is made of ice blue Italian leather "Alaska," and the pen loop is made of ice blue vegetable-tanned leather, hand-stitched. The stitching color is ice blue. The surface has a waxy finish, giving it a slightly white appearance, but the original leather color is ice blue (see image 8). As you use it, the wax will penetrate or wear off, gradually revealing the original color of the leather. *Images 9-12 are for illustration purposes only. *This listing is for the pen holder refill only. The notebook and pen are not included. **Size Guide** The photos show the pen holder with a "uni-ball one P (W13.9 x D19.2 x H116.8mm)" and a "Pentel ENERGEL (W11 x D16 x H147mm)." Pens with a barrel diameter of up to approximately 14mm can be used. **Leather** The leather used is Alaska Belly, an Italian leather that has been dyed throughout and infused with wax, containing plenty of oil. The white wax on the surface will penetrate the leather over time, allowing you to enjoy a unique aging process. Due to the natural shrinkage, the grain may vary depending on the area, giving it a unique appearance. --- ● Size (Outer Dimensions) Length: Approximately 10.5cm Width: Approximately 6.4cm Width (Pen Loop): Approximately 8.5cm ● Quality As it is a natural material, there may be scratches, wrinkles, and stains on the surface.
