This is a vegetable-tanned natural leather glasses case. It has a moderate firmness, so it won't be crushed even if you put it in your bag. You can see the aging process as you use it, and it will eventually turn a glossy brown color due to sun tanning and hand oils. The size is 18cm wide, 8cm long, and 4cm thick. Because it is handmade, there may be scratches on the leather surface and color unevenness due to oiling. This is a leather with a pleasant feel that makes a creaking sound. - Material: Genuine leather - Color: Natural Thank you for viewing. #Leathercraft #NumeLeather (Vegetable-tanned leather)
