We bought the balloons for my sister's wedding and wanted them together, each with a card with congratulations guests can fly. The balloons themselves are very nice, but they wanted to, appended with the card, do not rise. The card I bought here on Amazon; they are really very easy, deshlab I was amazed when the balloons did not want to really fly. Fortunately, we had to get the helium bottle that we had worried a pack nomraler balloons for free and then improvised and even appended a normal heart to each balloon. Then the flies leave was no longer a problem.
