I've been using my dark magic girl keycaps on my main keys for about a month now. On the keypad, you'll see a mix of Magic Girl and Millennium Magic Girl.
Not only does it give me such joy looking down at my keyboard, and how it looks. The keys also feel great. The original keys on my keyboard where much higher, and so the lower-ish profile on these, make typing on it feel a lot more natural at my desk.
If I had to find anything to complain about, it's that for the dark magic girl keycaps are teal instead of pink on the left. But tbh, it doesn't bother me the more I get used to it.
I'd 100% buy these key caps again, and I love using it all day long, whether for work or gaming.
