Now, these are some really nice keycaps, although the font could really use some work...

"
Black Translucent PBT+POM Double Shot Keycap Set (Vortex)"

It's good enough to make this terrible toy (
Tesoro Lobera Supreme) I got for review feel like an actual grown's-up keyboard.
But I still bet it'd look better on an actual
Cherry MX RGB keyboard, since Double-Shot keycaps are even harder to backlit than your standard backlit key.
PS: Sorry for not using a nice proper board like some
Ducky Shine IV or something actually fully compatible, but it's the only
ANSI backlit keyboard I had available.
