This flesh tunnel is made from 316L stainless steel. The back flare unscrews for insertion. All gauges from 8g through 00g have a 5/16" wearable area. All gauges from 7/16" to 1" have a 3/8" wearable area.
I've usually worn captives in my lobes, these are my first tunnels I've ever purchased or put in my ears. They fit perfectly and it was very easy to put in and screw the back on. Not heavy and to my surprise even in the smaller size have a lot of sparkle. Great quality for the price! I will be purchasing more tunnels in the future.
