The Original Slinky Brand spring toy measures 2.75 inches in diameter, designed for easy handling by children ages 5 and up. Its distinctive coiled metal construction produces the recognizable "slinkity" sound during motion, supporting both play and educational exploration. The toy facilitates open-ended activities such as stretching, walking down stairs, and creative manipulation. Multiple Slinky toys in different sizes and materials can be combined for expanded play options, though each is sold separately. This classic toy has maintained its design since introduction, offering intergenerational play opportunities.
