8 surprises in each ball.

Frozen Ball says :1 ring, 4 Ponies, 1 tattoo, 1 Bag and 1 Surprise

The other themed balls are not marked but give directions for Tattoos.  I have no clue what is inside these mystery balls.

Let me know if you try for multiples and shipping seems off. Sometimes Ebay has been calculating shipping wrong.  Several should ship first class so it should probably be in the $4 or less range.
