Choose your balloon colours from the colour chart(s), type the colour names into the Colour(s) Choice box, add how many arrangements you require and click ‘Add To Cart’ button. Helium filled balloons have a life span of 12 to 16 hours, or to make them last extra-long, just choose to add our ultra hi float gel giving them a life span of 2 to 3 days. 18″ Foil helium balloons have a life span of 7 to 10 days and do not need a special treatment. Float times are estimates based on typical indoor conditions. Don’t forget you can also upgrade your base from the basic base. Base colours will be made to match balloon colour(s) choice.
