Fidget spinner

Plastic spinner

 A fidget spinner is a toy or small device that will be able to help curb unwanted habits such as nail-biting and smoking. Instead of fidgeting or biting your finger nails, simply grab the fidget spinner and spin it.  Hold the spinner in one hand and use the other hand to spin it rapidly using small continuous strikes to keep it spinning indefinitely.  With practice, spinners can be spun using one hand only using the fingers of one hand to stop and start spinning. These are perfect pocket pieces for people wanting something small, simple, discrete and fun.  It's also effective for focus, stress relief and deep thought.
