There may be warts and scars from before the cow's life, and it is difficult to cut out a part without any scratches or lumps. We use the cleanest parts as much as possible, but please understand that there may be some individual characteristics. (Especially on the back, blood vessels are likely to be visible) ● Because cream is applied during production, you do not need leather cream for a while, and it is sufficient to remove dirt with a cloth or brushing. If you wish to take care of it yourself, please let us know. We will provide you with the raw vegetable-tanned leather.
