This is a listing for a multi-segmented cube, the Dian Sheng Soler 6x6 M (DianSheng Solar 6x6 Magnetic). I've only used it for about 2 minutes after purchasing it. From what I can see, there are no burrs or impurities. It's in relatively clean condition. The turning feel isn't extremely fast, but it's perfectly fine for solving it normally. There are no issues with the rotation. If you'd like me to add more photos, please feel free to comment. Thank you!
