The DaYan Mini ZhanChi 42mm version is the smallest version of the DaYan ZhanChi line. This cube is much smaller than a normal cube but is noticeably larger than keychain cubes. DaYan made this size of the ZhanChi in Black and White because 42mm is competition legal, making it perfect for children or people with smaller hands. Though it might be tiny, it performs exactly like a ZhanChi. The turning, the cutting, and the feel are all incredibly fast and smooth. It's crazy fun to solve and incredibly portable while packing the same performance as the original ZhanChi.
Jordan rated this puzzle 5-stars: "This cube shocked be as soon as I opened it. For a mini cube, it moves insanely fast. The portability is also very convenient. My brother even wanted to trade his full size cube for this little one. I am very satisfied with it"
