This item is a Russian Roly Poly doll, also known as a Nevalyashka. Unlike standard Matryoshka nesting dolls that open, these are typically solid wooden dolls with a weighted, rounded base that allows them to wobble and always return to an upright position. Many of these dolls also function as musical toys or chimes, producing a gentle sound when they are rocked or spun. Similar hand-painted dolls, often featuring detailed traditional Russian or Ukrainian motifs like floral wreaths and folk attire, this poly roly is approximately 4 inches tall and 3 inches wide. The musical chime is very lively and would be a better bell to call someone.
