I purchased these a while ago because I liked that they were simple and its hard to find inexpensive tunnels. When they arrived one already had a stone missing and when I touched where the empty whole was two more fell out on my finger. I contacted the company (who's customer service was very reasonable) for a new pair but was told that was their last set in my size and so they allowed me to choose another pair that they would send me for free along with a coupon for 10% off my next purchase. I struggled for days trying to decide what pair to replace them with because I honestly didn't like anything else the company offered. After making up my mind they shipped the new pair and coupon without a hassle but i have literally never worn the new pair. I just didn't want them. I should have just taken a refund. Overall dealing with customer service was good but the products are disappointing.
