Kwikshop

The object in this photo might not look like a ring to you, but it is — just add ink. This "Stempelschmuck" from Kwikshop, a Berlin store with walk-up window access only, is a rubber stamp you can use to temporarily brand yourself with one of four words: goldring, diamantring (both self-explanatory), verlobungsring (engagement ring) or ehering (wedding ring). But at just €5 per stamp, why limit yourself?
