Clean Hand is a package that can avoids people touching food directly when they eat packaged food. Using way is also simple：Firstly, tear out two corners of the package. Secondly, turn the corner outside in and fasten it on the fingers by black string. After doing these, people will eat packaged food without worrying about if their hands are clean or not. And after eating, people do not have to wash their hands (because hands are clean). This new package will be convenient for people and it also protects us from disease caused by unclean hands.
