Lui Interior Door Knob Set

Lui Door Knob Set by Verum Italy is defined by its rounded conical base and flat, angled face. The interplay of these two forms offers a refined, modern take on the traditional door knob. Part of the Nuda collection, Lui balances precision and simplicity in a clean, rose-less design. Made in Italy.

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