Not harsh, not cheap, just... nice to look at.
JadeGlow is PC — polycarbonate, the same stuff they make high-end headphone ear cups out of. It's naturally translucent with a frosted matte feel that your fingertips actually want to stay on.
Four colors, each one named after the thing it actually looks like on a lit-up desk. Cloud White. Celadon Mist. Blossom Pink. Ice Blue. Pick one or mix them.
PC keycaps are annoying to manufacture. They warp if the molding temp is off by 3 degrees. We had to scrap two batches before these were right. They're not cheap to make, and they're not cheap to buy — but if you want that soft-glow, jade-like feel on your desk, this is the only way to get it.
