I started with two coats of Orly Matte Vinyl. I loveeee it! It's black with no shininess at all. I've heard that KO Flatte Black is "blacker" but I haven't tried it and I think I'm pretty happy with the Orly.
Then I konaded some chains with China Glaze Millennium and plate BM12
It's far from perfect, but you can't really tell IRL. I think the matte base made it harder to konad on since it seemed like the polish didn't want to stick to it. I really do like the way it turned out though :D
