A mug is a mug, right? Sometimes it is. However, sometimes it's an expression of love, an expression of creativity. And sometimes, it's an expression of hilarity. This custom 2 sister mug embodies all three expressions, which makes it the best possible way to show your sister that you love her and that you're always looking out for her by making fun of her at the same time. An eloquent way to show those feelings without having to say a word, this "There Is No Better Friend Than A Sister And There Is No Better Sister Than You!" mug will have your back!
