Guess what is this?Ok,i'm not sure what they call for this stuff.But i called it vibrator.And, i get this as goodies from my boss birthday party last week.
At first I'm really not sure what the function , but after u twist this ball,it will be vibrate and realized it is good for the massage or if you feel sleepy in the office.Just twist and put at your neck or your eyes.
Its really useful.
Somehow,its look like king of fruits,Durian..hehehe..
