Thank you for viewing this item. Maremma leather is vegetable-tanned cowhide produced by the Italian tannery Walpier. It is rich in oil and characterized by a unique color unevenness and aging process due to the pull-up finish. It contains more than twice the oil of Buttero leather, and as you use it, the luster increases and the color deepens. It has a zipper so you can also put in coins. I created this thinking it would be useful when riding a motorcycle on a skyline (where cash is often the only option). Thank you. *Please note that returns and refunds are not accepted.
