You may also want to check out these from Signature Plastics, aka Pimp My Keyboard (PMK). They're offered in different translucent colors and they've also got individuals available as well if you want to mix and match.
I bought that 104 keys set + 2 blue caps from PMK some years ago and it is ANSI layout, Norz want a ISO set. The 4 (wasd) last caps and Up , Down, Left and Right Arrow caps are from old Qwerkeys/UK.

I guess you'd have to use an opaque ISO enter =/
I have no problems with usin ANSI keycaps sets, I use ANSI k - boards, we have/usin the not so good hopeless terrible ISO/Nordic layout here in Sweden, it is hopeless to find good lookin keycaps sets to that layout. That's why I use ANSI k - boards, no problems to find keycaps sets for that layout. Ok I have Jukebox SA set in both ANSI and ISO/Nordic layouts. TS ordered a CM Masterkeys Pro S RGB in ISO/Europe layout Also a problem is the ISO Left Shift, it is smaller than the ANSI Left Shift. Another problem with the ISO layout is all the different language layouts: ISO/UK, ISO/German, ISO/Nordic (Sweden, Denmark, Finland and Norway, havin this 3 letters: Ö, Ä and Å on the keycaps) + some more.
