Studex butterfly backs
Studex earrings come with two slightly different butterfly backs depending on the range. Understandably this can cause some confusion about whether the earrings are genuine. Both styles are but if you're in any doubt you can always contact Studex directly.
The Studex Sensitive and Studex Tiny Tips earrings have smaller, smooth, more oval shaped backs which aren't big enough for the brand name to be engraved.
Studex Plus piercing earrings, System 75 piercing earrings and the spare backs we sell are larger, round backs usually (but not always) with the brand engraved on them.
