There are two sizes of the Marvel's Avengers Thor Hammer. I ordered this one, the smaller one. It's a great size for a toddler (2 years) to child aged 8-10 years to carry. The length is 16" (not including the 6" strap) and is super lightweight. Although there's no suggested age or warning labels on the hammer, the strap looks flimsy and the hammer itself is bulky.
