Not that I would know, but taking apart a Rubik’s Cube and putting it back together again is sure to cause a certain amount of stress in the plastic parts over time. While such an activity may facilitate in the solving of the cube, it does nothing for having it stay a cohesive whole during use. If you’re looking for a gift for compulsive cube-solvers, perhaps this Rubik’s Cube Mug will do. While the mug won’t actually need any solving, at least it won’t fall apart in your hands.
