This is a very well made production item. When produced it looks like a giant ladies hat that can be worn. Each hat measures about 18" in diameter, and you would need to produce just 5-6 of these to fill the stage.
Though the hat looks very big when produced, when folded it hardly occupies any space. A folded hat is less than 6" in diameter and is less than 0.5" thick. You can easily hide a couple of these under your jacket.
Heavy steel coils are used in the construction of these hats to help it expand instantly and to help them retain their shape for ages. Comes in Pink, Red & Yellow. Specify color when ordering.
