I love the design of these tunnels, they are thin and lightweight but still sturdy and the design is very beautiful. I love the way the hammered texture catches the light and makes these tunnels shine. My only complaint with these is that the back flares are rather small, only about 1mm from the gauge size by my personal measurement using calipers. Initially I was concerned that they might be prone to falling out, but despite the size of the front flare and the smaller back flare, the weight is balanced and I did not have this issue while wearing them. The overall sizing from the saddle measurement is accurate. I would have preferred a slightly larger back flare to ensure that they are secure, but overall these tunnels are still really beautiful and I enjoy wearing them.
