This is the same keycap set you can find under the name "Wormier Low Profile Keycaps" on amazon for $21 dollars. All I did was take the original space bar out and swap it onto my Nuphy Air75 V2 because I couldn't stand the yellow space bar it comes with. I added that yellow space bar into this set instead and I'm just selling it for less. The funny part is nuphys yellow space bar is honestly a better keycap in feel, quality, and sound, I just couldn't deal with the color.
