I can't say when exactly the product will be available. I am hoping that it will be resolved within a week, but it could take as long as a month to resolve. I am sorry for the inconvenience. If you are in need of a Circle Pad soon, I recommend looking at the 3DStick+: https://www.shapeways.com/product/76RHQ7ZEW/3dstick-metal-3ds-circle-pad
As for one that resembles chrome black, the closest is probably polished grey. Polished grey is not as dark as chrome black, and doesn't have a mirror finish, but it's still probably closest.
