These tiny fans you were around your neck. If you look at the picture the two skinny things that look like legs rest against your chest when wearing. For a personal fan. They work well. I ended up buying rechargeable batteries because they didn't last long. Where I work they keep it to warm for me. 21C is too warm to cashier. I ended up buying a few different kinds of fans which I will be reviewing
These were available at Dollar Tree and Dollarama for $1.25
