Sen-chi is your signature companion on the move, a car reed diffuser that carries the essence of Senchi into every journey. Notes of clementine introduce a soft, uplifting citrus brightness as you drive, keeping the cabin feeling clean and lightly energised. At the centre, jasmine adds a velvety floral warmth that feels intimate and refined rather than overpowering. Cedarwood anchors the blend with a dry, woody calm, giving the fragrance a serene depth that lingers gently in the background.
Handcrafted in Sydney with 100% essential oils, this low-maintenance diffuser is designed to subtly scent your car with a modern, composed aura. Plug sen-chi into your car air vent to elevate daily commutes, long drives, and late-night trips with a sense of quiet balance and considered luxury.

Our hand-crafted fragrances
Each fragrance blend is hand-crafted in Sydney by Luke, using premium fragrance and essential oils sourced locally.
We wanted to create a unique collection of fragrances that would suit most people. But keeping a fresh botanical element to each one.
How long will it last
Generally 3 months.
Each diffuser blend has a different fragrance and essential oil mix, so we've done our best to create the right mixture to suit in-car use.
Some blends may last longer than others but generally we have seen them last for approx 3 months
Note* If your car is always parked outside in the hot sun, you may notice the reeds dry out quicker and soak through more of the oils than a car that's parked underground.
Can i get refills?
Yes. We have 60ml refill bottles for your car diffuser.
This will give you x3 20ml diffuser refills.
