I wasn't sure when I placed the order if I had ordered the correct amount.  Thought it was only one arriving.  Was pleased when the box arrives an there are like 20 in the box.  They are lightweight, so it helps when you put them on the tree because Christmas Balls tend to be heavy.
I also used them as stencil to spray fake snow on my windows. 
So as you can see, you can use these in several ways.  Next time I will get extras so I can turn them into napkin rings. 

Pros: Lighweight
Cons: Hanging cord provided is not strong at all
