Review on Balloon Birthday Decoration Balloons Wedding by Jeremy Taylor

Twice I have purchased Revain mylar balloons. Twice they do NOT swim with a store bought helium tank. I bought a few from Dollar Tree (they are full) and their balloons are still flying a week later. The only difference is perhaps the helium used. I bought a pre-filled helium tank so I can inflate the balloons myself. So either the helium in the new tank is of poor quality or the Revain tanks. I will experiment. If the party shop fills my Revain balloons for me, I'll know for sure. I need to know. keep you informed.
