Oksa rice grain mocha cup and saucer

The set of twelve suede cups has been used in my childhood at our family’s guest parties but rarely. The cups are stored in a cupboard or indoors in a cardboard box. At the bottom of the sets are Arabic and the designer's initials, FHKj. One of the inserts has a crack at the outer edge (of which there is a picture). I don’t know what the dishes have looked like new, but on the other hand I can’t see anything wrong with them.
