Is titanium good for a new nose piercing?

Yes. Titanium is one of the metals piercers recommend for healing piercings because it is lightweight and low in nickel, which is the common allergen. This set is made of titanium and described as allergy-free.

What is the difference between 18G and 20G here?

18G is slightly thicker than 20G. Most nostril piercings are done at 20G or 18G, so check which gauge your piercing was done at before ordering.

What does a flat top stud look like?

The top is a flat disc rather than a ball or a gem, so it sits low and close to the skin. That makes it a discreet choice for everyday wear.

How many studs come in the set?

Two. The set is sold as a pair, so you get two studs in the gauge you choose.

Can I wear these in a healed piercing?

Yes. Titanium is fine for healed piercings too, and the plain flat top suits daily wear. The main thing to watch is the fit, since a corkscrew back can work loose with movement.
