MoYu Mini Screwdriver Blue - Puzzle Tension Tool

With MoYu's mini screwdriver, you can easily adjust the screw in your speedcube if you want to loosen or tighten it. Gently remove the surface of the center piece and turn the screw a few times. Rotate the side between each turn to check if it feels right. Note that looser cubes are more prone to "popping" (pieces falling off the core), but they can still be reassembled. If you find your cube popping frequently, it may be beneficial to tighten the screws slightly.
