You won't find any of our range of hardware anywhere else as we design our own collection. What we design and make is exactly what I would like in my own home and in some cases exactly what I have there. We use a range of different materials, rough cast metal, thick glossy enamel, brass, palmwood, resin, birch, ceramic and brass, but whatever the material, I always keep it simple and sophisticated. This circular door knob knob is a ball shape - satisfying in the hand - in clear glass exquisitely marbled through in black and white glass, with a brushed nickel stem.
