Installed these on a Ducky Shine; no missing keys luckily! Caps lock definitely seems to be upside-down though! No idea what the neat blob key is, but it (plus the volume keys) was a useful replacement for the 1x/2x/3x/4x keys in the top right.
They look great!
MugenI had wondered long and hard about what that blob was. Thanks!
Did a bit of research over the weekend regarding these keycaps. Traced them down to a product announcement post on KBtalKing. It's a Taiwanese website, I'm not sure who they are, but I see the same keycap set, complete with the squirrel keycap, on one of the threads. KBtalKing's logo is a squirrel (side profile, bushy tail on left) and it is kind of similar to this keycap. The KBtalKing set comes in a cylindrical container which, while it looks nice, I'm perfectly happy not to receive in exchange for a few dollars less.
Website is in Traditional Chinese but has lots of photos. If anyone in subsequent drops wants some great photos : http://kbtalking.cool3c.com/article/83141
They look great!
