Nose screw with half ball in your choice of color.

This is a fabulous nose screw available in five different colors and two gauge sizes. It's made of surgical steel with a layer of titanium in different colors. Choose your nose stud in your choice of color - the price is so low, that if you can't decide on a single one and buy more than one, your economy won't be affected. ;-)

The shape of this screw is ideal for those who like changing their jewelry often. Put the end of the stud in your piercing and slightly twist it to insert it and securely fit it in your inner nostril. 

Note that it's available in two different gauge sizes: 20g and 18g (0.8 and 1 mm), so you must select the gauge that fits your piercing.
