PTFE tape in white. PTFE tape is commonly used to increase the size (gauge) of an ear lobe piercing, by wrapping the tape around a plug, tunnel or stretcher. The tape measures 12mm wide and is 0.075mm thick. The total length of the tape is 12 metres and the roll comes complete with a clip-on cover to keep the tape clean and tidy.
