The balloons are supplied flat packed ready to be filled with helium by you.
Canisters of helium are available as an add on for £32.50. Each canister will fill 1 giant 3-foot balloon to 70cm and will float for 3-5 days.
For inflation, our recommendation would be to have 2 chairs and measure a space of 70cms between them. Blow the balloon up with the helium in between the 2 chairs until it is touching each chair and then you will know it is filled to exactly the right size.
The balloons are made from excellent quality latex - the balloon choice of professionals - and filled with vibrant, luxury tissue paper.
