Soap Interior Door Knob Set

Soap Door Knob Set from Verum Italy features a solid, stone-like form shaped for a comfortable, symmetrical grip. Designed to mount directly onto the door without a rose, it maintains a clean and modern aesthetic. As part of the Nuda collection, Soap embodies the Verum philosophy of quiet, integrated design. Made in Italy.

A key design feature is the absence of a rose backplate, making these handles unsuitable for pre-bored doors.
