Size
Exact size for a wood animated puzzle that uses ball bearing this size . The one you turn the hand crank and the balls go down different paths. I had lost a couple and measured diameter and they were 11 mm and these where exact size . Verified with calipers.

As advertised
The media could not be loaded. I bought these steel balls to replace the ones I lost with the Marble Run I was building. They were exactly the size I needed

Perfect for the project
I got these for a marble machine for my dad, I'm super glad they were the right size. The price 9s fair so if any get lost it's easy to replace.
