There are still several colors available on hknowstore. Most of them are sold out, but there are still a few that are still available.
The different colors of master kilominx's on hknowstore are not "real" limited edition. I purposed this idear to Calvin over a year and a half ago, and for me and a couple of other person he first did 1 batch (using 12 colored plastic master kilominx), and at my surprise he did a second batch. The first time he did it, he told me that it was a lot of work, but for certain reason he did another batch. My personnal opinion "just go with the color you like" yes limited edition are cool, but if you don't like the color, why are you buying it?
My grapes are making noises right now. They keep saying drink me, drink me.
