I love the look of these chairs but they started chipping right away. They also show ALL dust, dirt, grime, etc. I have a lot of natural light in my dining room, in hind sight black wasn't the smartest choice. In a darker room they wouldn't show every speck. 
But I'm not sure how to fix the chipping paint. You get what you pay for and these were not expensive. Design wise, they are beautiful. Make and functionality, they are sub par.
