Fidget spinners are the latest craze. While your customers may not want to win one, their kids would love another one. There are thousands of choices and prices from under $2 to above $20.
Make sure you pay attention to delivery date as lower cost items often come from China and have shipping times longer than 1 month. Also, a $2 fidget spinner is not going to be high quality. Plan on paying more than $10 if you want the higher quality bearings and longer spin times.
