Store/keep them at room temperature so they last as long as possible. Do not keep them near a radiator, window or in cars. Protect them from direct sun/heat as it can cause balloons to expand and pop.
Please be gentle when transporting them, if they are forced into a car or small space they may burst. Only keep them in cars for the period of transporting and remove them as soon as possible. Do not keep them in a car overnight.
Extreme cold temperature will temporarily shrink foil balloons. However once they are moved to room temperature they are restored.
If left outside or exposed to sun or heat they will show signs of oxidisation (can become a matte colour and lose their shine).
Protect balloons from sharp objects or rough surfaces as this is likely to puncture and deflate the balloon.
Balloons are made up to 24 hours in advance of your date to check for any faults and ensure any faults are corrected.
Once balloons have been collected / delivered they are no longer my responsibility.
