mookothekingHey hello!
I'm yet to witness shine on SA keycaps, safe to say it depends entirely on how you use/take care of the keycaps and hygiene.
The natural oils from the human skin is what actually deteriorates plastic over extensive use and years.
Let me know if you have any other questions!
mookothekingI have a set of SA caps from this manufacturer. Yes, they have a bit of shine on them after heavy daily use. But they still look and feel great.
