This listing is for a single 18K PVD plated G23 (ASTM F136) implant grade titanium push-pin flat back stud.
Titanium is one of the best materials you can get without going into gold. Sensitivity wise it is just as good as 14K gold.
Hypoallergenic, tarnish resistant. You can leave them in for as long as you would like. We do recommend wiping them down regularly with the jewelry wipe to keep them nice and vibrant.
