This is a handmade pen case made from vegetable-tanned leather (nume leather) that can hold three pens. It will protect your pens from scratches, prevent ink from leaking in your bag, and keep them from getting lost. 【About Untreated Nume Leather】 This is "kiji" leather, which is in its pure state without any surface treatment. It is a material that allows you to enjoy the aging process, where the leather gradually changes to an amber color over time, which is unique to nume leather. "Kiji" refers to the color close to the skin tone of the material that has not been dyed. We have applied "neatsfoot oil" for moisturizing and protection, so please enjoy the gradual color change over time. *Please note that there is one spot of a stain from before the animal's life. Please take a look at the images and make your purchase with your understanding. *Product Details* ◇ Thickness: Approximately 1.3mm ◇ Type: Cowhide, vegetable-tanned nume leather ◇ Texture: Firm ◇ Sewing: Machine sewing ◇ Width: Approximately 5cm, Length: 15.5cm The items for sale are all handmade, including cutting and sewing.
