They're just small little toys that spin. I thought maybe they'd light up or something, but I just looked up a video and they're literally just little things you flick with your fingers to make spin.
Sounds to me like they were made for sufferers of certain mental illnesses. Helps them with their ability to focus, apparently. Very nice.
Yeah I understand google is free but I had to get offline and go to the store. I thought it would be easier to make a forum and view the email whenever I get the email to my phone haha.
And Animalcrossingperson, I have heard of them being toys more than helpful, my boyfriend made a joke asking if I wanted one, and I said "no what even is one"
his response was a "new popular childrens toy"... I also seen a picture of one and it looked like it could cut off a finger haha (ik they cant)
