The seller was prompt and the product is as advertised. It works but it is BLACK. If your leather is not jet black, this will be difficult to accept. It dries quickly, which is great when it’s the right color, but can be maddeningly frustrating if it doesn’t match the leather. Be aware that your leather may ‘look’ black to you but I guarantee this product is blacker. When they say "try it on an inconspicuous spot”, follow that advice. Also use this product in a brightly lit space with good ventilation.
