Hello, normally an, inflated latex balloon with helium should last 8 to 16 hours. Foil helium balloon can retain for much longer, often remaining inflated for 3 days to 3 weeks . It all depends where you place them and the room temperature they are placed in. You should let us know in 8 hours not after 20 hours to get 100% refund back, how ever you should not carry the balloons back with the motorbike, at 3 pm which the temperature is very hot. It's policy and a procedure that must be followed. It's fair for both the shop and the customer, so we request your cooperation in bringing your passport and making an appointment with the police.
