Thirty Three
A cold face wipe, and the small refrigerator that keeps it. Lift the lid, take one, close it again. That’s the whole product.
Drag to turn it. Click it to open.
Designed to disappear
No screen, no app, no Wi-Fi. A soft light that turns frost-white when the cassette is cold. The technology should vanish; the object should feel inevitable.
It sits low and wide, like a stone box. Roughly the footprint of a hardback book. The lid lifts on a rear hinge, and the next sachet rises to meet your hand.
