Expansion pin
An expansion pin (also known as a taper ) is a conical hard plastic or metal pin that is used both for stretching piercings and for easier insertion of jewelry into already stretched piercings. Mostly they are made of stainless steel or acrylic .
Expansion pins are available in different sizes. They are defined by the larger end and there often have a hollow or are flattened so that the jewelry to be inserted can be attached better. There are also expansion pins that have a thread at the wide end onto which the jewelry can be screwed so that it can be inserted seamlessly into the ear hole. Their length varies between five and ten centimeters.
Stretch pens should only be used to stretch and insert jewelry, not as permanent jewelry. The long sticking out stick is not only uncomfortable, but can also irritate the sensitive skin within the puncture canal when moving and cause inflammation. Stainless steel tapers in particular also pull the canal down on one side, which can lead to deformation and thinning. The lighter acrylic, on the other hand, is not recommended for long periods of wear due to the inability to sterilize and the possible intolerance of the skin.
Alternatively, there are also circular expansion sickles. These can be worn permanently as jewelry during the stretching process and slowly pushed in as desired.
process
The expansion pin is first coated with lubricant and inserted into the puncture channel with the thinner side first, the jewelry is attached to the end of the expansion pin and thus seamlessly inserted into the puncture channel.
