Finish:Antique Pewter

When we moved to a 50s ranch, I really missed a lot of the detail from our previous home, a big hundred year old beauty. These porcelain knobs remind me of the old world charm I miss - very pretty and solidly built.

Same issue as with the privacy knobs, a screw head broke off inside the rosette during install, but it's completely functional and looks great.

So beautiful! Easy to install, but on several of these the screw heads broke off in the rosette. Luckily we like them!
