I love that these come in different lengths and different gauge thicknesses. I have bought extras of the 18 gauge and I just bought some 16 gauge for my newly pierced conch and midi. I believe I’m going purchase a 20 gauge because my third holes just don’t love the 18s. I do wish you would make 4 mm length for forward helix piercings. The five is just a little too long, but it does work. Both medals have been great in my ears and have not irritated them at all, and I have very sensitive ear.
