• This bullet is not only powerful but it has a teardrop shaped power pack. 
• It's a fabulous design. 
• It cradles right into the palm of the hand but the multi-speed control dial can be accessed on either side of the power pack. 
• Requires 2 AA size batteries, not included. 
• The bullet is 2 1/4" X 1". 
• Remember that it's the quality of the product that counts not the packaging!
