The Original Slinky Brand Giant Metal Slinky Kids Spring ToyThe Original Slinky Brand Giant Metal Slinky is the big daddy of the family and continues to be a constant entertainer as it walks down stairs or comes alive in a child's hands. This version is 70 percent larger than the original Slinky, made of metal and stretches farther, flips higher and walks down taller steps while making that classic Slinky sound. Recommended for children 5 years of age and older.
