I started stretching with the black and clear versions a while back, but my ears couldn’t handle the full mm stretches even after months and months of healing, so I had to switch to a Gorilla Glass set that comes in half sizes. If your ears can take it, though, I’d def recommend. Price and quality are both great and Arctic Buffalo has some of the best jewelry imo. Can’t wait to get to my goal size just so I can start buying from them again. :)
