Just what I order. Fits and feels great.

Jim Newman
Ordered 4g but received 6g

Would have tried to file a return but had already opened the item before I noticed it wasn't 4g.

Great customer service and excellent variety

I’ve placed two orders recently and both were filled quickly and shipped out within two days of ordering. I’m pleased with the quality of the product and will continue to order from Tulsa Body Jewelry

Precision Manufacturing!

The tolerances between the ring and the balls is so precise that I was wondering if it was one piece until I managed to get a good enough grip to get one of the ballls unscrewed. This is my first titanium piece and I am amazed at how much more well made it is than all my stainless steel rings of smaller gauge. And so light! I will miss the weight to be honest.
