The outer inflatable section (22) is made of a flexible plastic material. Inside, three corner reflectors are formed from a flexible reflecting material with a central section, and two sections (18) at right angles to the central section with flaps attached to the outer mini-balloon surface. The front of the mini-balloon has a securing grid (28) for the wire (29) to hold the balloon aloft, and an inserted tube to pump the balloon up. ADVANTAGE - Less bulky in its inflated and non-inflated state.
