Having been involved with the advertising giant inflatable balloon market for over 25 years one question that has been asked over and over again is “how long does an inflatable balloon last?” The answer is it varies from customer to customer. If it is taken care of and cleaned regularly it can last 10 years easily. If it is abused they can be ruined in a month.The following image is of “Theo”, an inflatable balloon we made over 10 years ago for WGBH Boston. He was cleaned and stored properly after each use so he never developed mildew. He is ready to be used for the next 10 years and will keep on going as long as he is shown the love he deserves.
