You're looking at a pen sleeve made for full-sized pens and fountain pens up to 14 cm in length. The edge of the pen sleeve is curved for a unique look and a better fit. The pen sleeve is constructed of natural vegetable-tanned cow leather that will develop a unique patina as it ages. Edges are burnished and beveled.
About the leather: Made from wonderfully tanned vegetable tanned cow leather. Vegetable tanning is a traditional way of tanning using tannic acids naturally found from plant species. The natural appearance before painted, has a slightly brownish tinge over a beige color, with a natural, woody and earthy smell. Due to the nature of the tannins, a unique patina will develop and "carmelize" over time.
