The Geometry of Thin

One continuous aluminum shell

Chemically etched from a single blank — no seams, no joints, 0.8 mm wall thickness throughout.

The flip is calibrated theater

Spring-loaded cam rated for 100,000 open cycles. Every motion timed to 0.3 s flat.

Keypad cut from the chassis itself

Laser-etched through the same aluminum body. Backlit via micro-perforations invisible at arm’s length.

Fourteen millimeters, nothing wasted

Every component re-engineered to fit the thinnest profile ever produced in the category.
