Činka do pupku s kamienkami a vnútorným závitom.

This belly button ring has everything you would want: it's internally threaded, made of titanium, and features sparkling stones.

An internal thread is preferable to an external thread because the possibility of scraping the skin around your piercing during insertion is reduced. Titanium is one of the best materials when it comes to piercing jewelry. It doesn't contain nickel traces, so you can also use it as a first-time piece. 

And what can be said about sparkling stones? Everybody likes stones that reflect light in every direction. The stones are held in place by three tiny prongs, so no glue has been used to secure them. 

The stones are available in a variety of colors, as you can see in the pictures above. Besides, the model with clear stones is available in two different bar lengths.
