Matryoshka is a set of dolls of decreasing sizes placed one inside the other.
I used this typical russian doll as a gift box (made of vinyl) for a little bottle of an alcohol. It is based on the word spirit (which means in english alcohol and also soul). Matryoshka consists of four parts. Firstly you´ll get just the dressed man doll. But when you open dressed man you will get nude man, when you open nude man you will get man without skin, when you open skinless man you´ll get skeleton, when you´ll open skeleton you will get the spirit.
Dressed man → nude man → skinless man → skeleton → soul
