Use the code "tsm" to save 2usd if you want to buy the premium cube.
GuoGuan team has released a new 2x2 in September, 2020, called Xinghen TSM. "TS" means "three sizes" literally. I'm really excited to share how their new size adjustment technology works! They make a special design on the corner pieces with unique size adjustment mechanism so that you can choose the sizes at your preference by using the tool (50mm,50.75mm and 51.5mm 3 choices available). They also updated the anti-sticky concave which makes it more stable and durable. What's more, the reasonable magnet layout provides you a comfortable and controllable feeling while solving the cube. Finally, the unified edge design avoids deformation and becomes more stable.
