Lefun Ghost Pyraminx, but actually a Ghost Skewb in the shape of a tetrahedron. Notice the presence of the other 4 corners (which don't exist on a regular pyraminx). Ghost Jing's Pyraminx then, if one is to be pedantic.
I hope this functions well; the FangCun Ghost Skewb (Tony Fisher's Golden Cube) didn't have torpedoes on the skewb centers and it popped literally on every solve, which is a lot of headache for a ghost
skewb with all the orientation problems.
Also, to whom it may concern, the cube in the post quoted below turned out to be a
LimCube Mini 6x6 indeed. 54.6 mm! I believe they have an old 3x3 and 2x2 at exactly this size.
Currently available at HKNowStore, soon at other stores too, I guess. Seems to be made only in stickerless, which honestly kind of sucks. I was hoping for a black-with-stickers to complete a certain sub-collection. Does anyone have experience with dying stickerless plastic into black? Will it be consistent, or am I better off obtaining a force cube (i.e. fully white) and dying
that one?
