The real interest of a handspinner lies in its ability to take care of your hands. Gone are the hours you spend biting your nails or spinning your pen at the risk of dropping it on your desk. Without making (too much) noise, it will turn between your fingers without even you realize it. You can even pose it in front of you and watch it turn!
since it slips easily into the hand and occupies the fingers … it can help those who smoke to stop. To get rid of the gesture, instead of taking a cigarette, smokers can easily catch their hand spinner and rotate it to take care of. This will not reduce the craving for nicotine, but can be an interesting tool for those who smoke and would have trouble keeping their hands inactive!
But it's not only its virtue: it's also a very good anti-stress, which will allow you to concentrate and calm down in any circumstance. This is why it is particularly appreciated by those who work in an open space and try to focus on a spot without annoying their neighbors!
