10 Grips per box
 
The front end of the machine, the grip, comes in the form of a single use E.O. gas sterilized ratcheting grip, complete with an o-ring installed in each for extra stability and peace of mind, as well as an entirely enclosed drive system; which means when you finish your work, you simply keep the motor and dispose of the rest of the machine aka the grip.
 
One grip uses up no more plastic than an average tube.
