A common problem people encounter with their traditional rings, is that over time they start to change shape. They tend to become more of an oval shape and they lose their truly round shape. This is especially true with narrow rings. Unfortunately, this is just a natural process in the aging of the ring.
However, this does not happen with titanium rings. They keep their true shape. They do not bend. They do not distort. It would take a machine and a great amount of force to bend a titanium ring.
This becomes very nice when you consider that you can make rings as small as 2mm without worrying about them losing shape. In fact, the narrow titanium rings are VERY popular with women who want an elegant thin ring. With titanium rings you can get a truly narrow ring, and now have to worry about it distorting.
