The Bubble Popper Pen is a must have tool for any vinyl graphics installer or car wrapper. This pen is the right tool for the job and it is easy to hang on to since it clips to your shirt pocket like a ball-point pen. The needle point offers an ultra-sharp round tip that retracts and extends just like a ball point pen. This tool is used to put a pin hole (never a knife slit) into your vinyl, printed graphics or car wrap where a bubble or rivet might be to release the air and flatten the film graphic on to the substrate.
