The number 13 does not float! Material is too heavy!
Very disappointed in the  mylar number balloons. I went to the party store to fill them up with helium, and they are made so heavy, that they would not  float. I paid to fill them up even though they did not work. The rest of the decorations were great. Very disappointed in the 13  especially since you can't check to see if they work until party day.
