Berkeley Marker, Smooth Flat Handle, 3mm/3.25mm Diameter Markers, Overall Length 4-3/8" (110mm)

The Berkeley marker carries paired 3mm and 3.25mm reference rings on a single instrument, letting the surgeon choose between two closely spaced optical zone diameters during refractive marking. The smooth flat handle supports steady fingertip orientation through ink loading and contact. A 110mm body balances the dual‑ring head for clean impressions.
