I have multiple holes in my ears and on any given day may wear 1 pair or 4 pairs of studs or small hoops.
These studs are for when I am only wearing one or two pairs beause of their size, but they are very clear and the posts do not irritate my ears.  I have sensitive ears and they will swell when I wear the wrong earrings.  These did not hurt, itch or make my ears swell.  Good value for money.
