Best Ivy Cube on the market! There’s a ball core and UV coating on this cube! Out of the box the tension and elasticity is already set to 1 so no need to adjust the cube any further! If you need the cube to slow down then I guess you can tighten the cube but right out of the box it’s magnificent! The weird thing about this cube is the fact that the box says it’s a maple leaf cube but realistically it’s an Ivy Cube. Nonetheless buy this cube! You won’t regret it! Shipping takes 12 days so order it and just continue your life without thinking about it! I live in California and it’s like Christmas when cubes arrive for me! I highly suggest this Ivy cube over any other brand make or model, also dont buy the Moyu Smart Ivy cube since this cube can be solved in 10 moves, the ai interface is unnecessary haha!
