A "Nested Doll," also known as a Matryoshka doll, is a traditional Russian toy consisting of a set of wooden dolls of decreasing size placed one inside the other. Each doll is typically painted with colorful designs, often depicting folk themes or characters. The largest doll opens to reveal a smaller one inside, and this continues until the smallest doll, which is solid. These dolls symbolize family and unity, representing the idea of being connected yet distinct. The craftsmanship involved in creating Matryoshka dolls showcases the artistry of Russian culture, making them popular souvenirs and collectibles around the world.
