This is an electric shaver from Panasonic that uses dry cell batteries. I have tested its operation with a single AA battery before listing it. *The blades have not touched skin. It has been stored in its box for about 2 years. *Please refrain from purchasing if you are concerned about minor details or are overly sensitive, as this item has been stored by a private individual. By purchasing this item, you are considered to have agreed to the description on the product page.
