I've never heard of it before. Looks like it's $5.00 for 3 cubes on ebay. The packaging looks like the Balabushka chalk. Might be made in the same factory?
Doubtful it's any better than Triangle, Blue Diamond or Masters for the money but, I'd have to try it to be sure.
I'll be happy to review it if I get a free box to try.
Those are the guys that are trying to copy Kamui with the look alike tips.
I may get a box of that chalk to try though, from the looks it seems to be more like Diamond or Balabushka than Masters which I like. A bit finer grain and stick.
Actually, it looks EXACTLY like the Balabushka chalk down to the off center hole placement and the crumbly edges LOL
