This mug is made up of metal. It is not a good design to me because when you use it for drinking coffy it burns you and when drinking something cold it produce cold on your hands.
My improved design
This is the latest fashion vest it is my most iproved design because it has been made to stretch if someone can attempt to pull you by it it wont easyl break but instead it will stretch...and the moment you let it go it goes back to the normal structure. Its so flexible for most people to wear it. I just love it...wow.
