Esprit BT11R‑RY Colombo Design handle – contemporary rigor by Birgit Lohmann

Designed by Birgit Lohmann, the Esprit BT11R‑RY handle is an icon of minimalist style: the square and tapered lever integrates elegantly into a 50×50mm square rosette with an ultra‑flat thickness, offering a geometric profile with great visual impact. The design is intended to complement modern, contract and refined residential interiors.
