Only what belongs.
The products you use every morning and every evening deserve the same attention as the food you eat. We make them with that attention — to be part of the day, for as long as they last.
Presence
Design
Used for minutes, seen for hours — quiet, proportioned, good in the hand.
Every element earns its place, or it goes.
Substance
Materials and ingredients
Daily care, held to the standard of food: high grade, barely processed, free of plastic.
What plastic does in the body is still being mapped; we would rather not wait.
Intent
Health and way of living
Health is rarely one big decision; it is small habits, repeated twice a day for a lifetime.
What you eat, how you move, what touches you — one body keeps the account of all of it.
We do not believe in more products, only better ones.
Pure, and held back.
Rein is a Dutch word for pure — clean in the plain sense: nothing added, nothing left behind.
In English, a rein is what holds a horse back. Both meanings apply here. The products should be clean; making them asks for restraint.
That our first product has horsehair bristles is a coincidence. A good one.
REIN is a small studio in Amsterdam.
We write two letters a year, when there is something to show, and we answer our own mail.
