The secundrabad-based company, inflatable ideas, specialises in advertising vehicles of the inflatable variety. Products include balloons, product replicas, costumes, stalls, castles, etc. The standard helium balloon shapes are spheres of sizes 8, 10, 12 and 15 feet diameter, blimps of sizes 15, 20 and 25 feet in length and hot air balloon shapes in all colours. Shapes of balloons can be customised too. The balloons are made from high quality poly vinyl toy lamina sheets that retain gas for longer duration and give maximum life. Balloons are a popular medium of outdoor advertisement because the recall rate of the message displayed on the balloon is much greater than other conventional type of outdoor advertising media.
