Betty, the titanium frames are a Danish brand, Orgreen. They are very lightweight. This particular pair is the Pussycat but they have many different designs. They are quite expensive but the workmanship is amazing, and they have held up well for nearly 4 years.
When I was searching for them I visited a lot of different optical stores in my area to get a feel for what was available and what I liked best. I had heard of a couple specialty stores with high end frames that I looked at. I visited the store I got these frames at about 4 times after picking each pair out so that I could make sure they were truly the best, and that I wasn't making an impulse buy on something so costly.
