This is the Coffee Hanger and it is designed by Milan-based Amir Alizade. This is not a very practical function other than that you can hang it anywhere you can hang your clothes, but this is a very creative idea and a fun way to keep your coffee mugs.
These cups are made out of ceramics and have a hook in the place where the handle should be. The hook is made out of steel and has the same design of a hanger. I don't know if you can get these mugs in other colors, but you can get them in either blue or white.
