    My fault for not checking the size of this stud! It’s super tiny. Would be perfect for little kids or people with small ears.

    Hi Kathryn,

    Thank you for the honest feedback about the Tri-ball Flat Back Stud! We totally get how it can be disappointing when you're expecting something bigger and it turns out to be much smaller than you had in mind — sizing can definitely be tricky to gauge online sometimes.

    We're glad to hear that despite the size surprise, you still think it's a quality piece that would work well for others! Your feedback about it being perfect for smaller ears is actually really helpful for other customers who might be looking for something more delicate. Thanks again for taking the time to share your experience — it really helps other shoppers know what to expect!

    😘~ Elvie with Cords Club
