OUR WHY

My name is Marc. I designed this car diffuser as an object of presence.

I created this diffuser to bring quiet elegance into everyday driving — minimal in design, precise in detail, and filled with 100% perfume-quality oils that deliver a scent unlike anything you’ve ever experienced from a car diffuser.
