64inch Silver Number 5

These Giant 64 Inch Silver Number 5 Are Sure To Make A Great Impact. These Supershape Number Balloons Are Heat Sealed Half Way Up Dividing The Balloon In Two Halves, So The Top Half Can Then Be filled With Helium And The Bottom Half Filled With Air.

You can inflate the bottom part with air and the top with helium and they will float (so they shouldn't use much more helium than a standard giant foil number).  They will certainly make a statement at any party.
