Save money on your helium gas costs with the new Helium Saving Balloon Valve (HSV™) from B-Loony Ltd.
The clever little invention (international patent applied for) is inserted into the neck of a latex balloon, and works by drawing air into the balloon at the same time as inflating it with helium gas from a cylinder.
Tests have shown that the Helium Saving Valve, or HSV™ can save up to 30% of the amount of helium gas normally required to fill a latex balloon.
