calmarimo
Your living companion
A ritual of calm
Marimo are ancient moss balls that grow just a few millimeters per year. In Japan, they are cherished as symbols of love and good fortune — living companions passed down through generations.
Calmarimo was born in Zurich from a simple belief: that slowing down is a form of care. Each kit is a small invitation to pause, breathe, and connect with something quietly alive.
No batteries. No screens. Just water, light, and a little patience.

How to care
Fresh water
Change the water every one to two weeks. Tap water works — just let it sit for a day first.
Gentle light
Indirect sunlight is perfect. Avoid direct sun — marimo prefer the calm shade.
A little love
Roll your marimo gently now and then to keep its round shape. Talk to it if you like.
