QiYi WuJi 7×7
The QiYi MoFangGe WuJi is the latest 7×7 to hit the market. At 69.5mm across, it is around the size of most modern 7x7s, but at just 206 grams, it is also noticeably lighter. It also boasts several innovative design features, like single-piece construction, a capped design, and enlarged internal pieces for improved stability, among several other novel features.
The WuJi 7×7 was also used to set the new World Record 7×7 Average before it was released on the market.
