This are the landmarks I choosed for this ring:
New Palace, Mercedes Benz Arena, Opera House Stuttgart, Cannstatter Wasen, Stuttgart TV tower and the Mercedes Benz museum.
More Skyline - Cityscape rings here.
Please contact me, if you like another size and/or material and/or have other ideas.
Please double check your size. It is important, because these rings are pretty tall (aprox 11mm high) and maybe feels tighter then the usual rings.
