ANSWER: Dolls

Stack inside each other

A matryoshka doll is a Russian nesting doll which is a set of wooden dolls of decreasing size placed one inside the other.

Traditionally the outer layer is a woman, dressed in a sarafan, a long and shapeless traditional Russian peasant jumper dress. The figures inside may be of either gender; the smallest, innermost doll is typically a baby lathed from a single piece of wood. Much of the artistry is in the painting of each doll, which can be very elaborate. The dolls often follow a theme, aside from the typical traditional peasant girls, the themes vary, from fairy tale characters to Soviet leaders.
