The magician shows his hands empty. He forms one hand into a closed fist, reaches inside and starts to produce a shiny Mylar streamer. When stretched, the Mylar streamer measures approximately 12' or more in length! An amazing production! Just like mouth coils, but to be produced from a thumb tip. The price indicated is for a set of ten coils packaged in a hard plastic case. Each coil can be used only once, but the effect is well worth it. Just to see the bright eyed look of amazement on the spectators' faces when you produce a 12' streamer from your apparently empty hand. A lot from a little...the way production items should be.
