Five pieces.
One object.

Two chambers.
One seal.

Two independent compartments keep contents separate and protected. Each closes with a quarter-turn bayonet that magnets set home with a quiet click — metal seating on metal, engineered for an airtight seal with no gasket to age.

Press. Turn.
Click.

Align the lugs with the entry windows, press, and turn ninety degrees to the stop. The bayonet track is printed into the metal.

The last millimetre is not yours. Two recessed magnets — one in the cap, one in the body — find each other and set the cap into its metal-to-metal seat with a quiet, definite click.

Four nickel-plated NdFeB rings in all, two per joint. Their pockets and a solid divider keep them away from either chamber, and from the contents.

No spring, no clip, no gasket. One gesture in, the same gesture out. We call it the 90° Click.

Sized for real life.

It takes the space of a lipstick and carries like a fine pen. A Ø21.5 × 74.7 mm cylinder — at home in a handbag, a jacket, a pocket.

The bayonet is not machined.
It's printed.

Steel, drawn
out of the dark.

Electropolished to a mirror, weighted like an instrument. It holds the light, and gives almost none of it back.
