First off, I love these keycaps.
The green complements the off-white very well, and there are plenty of novelties in the box. I've used these on my Glorious GMMK Pro, and they work very well on full sized keyboard as well.
The quality of the keycaps are very good. Fairly thick, and they have a bit of a matte texture on them which I like.
The only thing to note is that the green color is not as dark and saturated as the photos suggest on https://www.momoka.co/forestofelf. They look closer to the photos seen on https://www.techpowerup.com/review/building-a-keyboard-6-momoka-switches-keycaps-epomaker-skyloong-gk87-kit/4.html. I would have preferred the other shade, but I'm also perfectly fine with the lighter, more pastel green I got.
Overall, these are one of my favorite keycap sets. Will be looking out for more by Momoka in the future!
