I received a blank "navy blue" kit today from the Korean seller on eBay, and I really recommend it.
The "navy blue" is so dark that it looks practically like black, unless you have something really black right next to it to compare against.
There are two 6.25u Space bars in the kit, one of which is a "universal" bar that fits not only some Leopold models but most others as well - including my Cherry G80-3000.
There are two centre-stemmed Caps Lock keys, one with a window and one that is stepped (1.5).
There is an extra 1.25u and an extra 1u key for the bottom row, so you would need only to add a L-shaped Return key to get a ISO set.
I did the "acetone test" on a few keys, and the keys passed, including the windowed keys and the space bars!
The profile is Cherry. The only differences are in the radiuses and sharpness of the edges to the top surface and that the sides are textured instead of gloss. There are sprues on the bottom of the keys that would make them look somewhat different if you compare them on a flat surface.
