The QiYi/MFG 3x3 Core is the same core that comes with the QiYi/MFG 3x3 cubes, like the QiYi Sail 3x3, Thunderclap V1 and V2, and the Valk 3. It is compatible with the Valk 3 Hardware Set.
This core is a brand new core that is non-threaded. It is threaded by the screw when the screw is inserted.

Our Promise to You
All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.
Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.
The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

I bought this core to replace the broken one that was in a Qiyi Ms 3x3 I had an idea that it might fit because it was the same brand but apparently not. Other Than That I am sure it would work great in any other cube. If any Cubicle staff is reading this would you mind letting me know if there is a certain core that fits the Qiyi Ms, Thanks!
