these should be standard on every set of AirPods. I ordered the wine colored one first and liked the fit of it so I ordered another one to go with a pair of shoes I had gotten for my birthday that matched perfect with the shoes. The color selection and the value of this set since it also comes with the strings/needles is great for my purpose. And no, I am not incentived in ANY WAY by promise of reward or discounts for leaving a positive review. DONT BUY (en especial sus fundas para celular), me decidí por comprarla a pesar de superar mi presupuesto . I purchased a day before Christmas and it has been even one month. Yes, it was over 30 days, but I would think that a towel rack should last longer than that. Consider these. I installed them myslef, and they look great.
