The 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.
