Prism is a square, highly elegant and practical zamak knob, providing an excellent one-finger grip. The contrast between the blunt shapes of the foot and the slim frontpiece gives it a personality that stands out from other knobs. Available in seven finishes – titanium black, brushed brass cava, matt white, matt black, polished titanium black, polished nickel and polished brass – it is a highly versatile design that classily blends in with all kinds of surroundings. It includes a non-twisting tip.
