This is the world’s greatest fidget toy. You can learn to solve a cube in just a few days online, and if you have long flights or stressful meetings in your life, this cube will make them disappear. This is one of the most expensive cubes on the market, but well worth it. Magnetic corners, and an internal rotation mechanism that’s nearly frictionless, makes this feel like a magical object when you hold it. There are versions with and without stickers. I like the stickerless version because there’s no fear of damaging the faces as I take it in and out of my bag dozens of times a day.
