Japanese designers Nendo are one of the most visible authors today. We like their conceptual packaging for a perfume.
It is quite older project, but we have used it in the context of our OKOLO for Japan poster some times ago as one of the best contemporary examples of Japanese minimalism. Called Clear Perfume Bottle for 1%, the bottle is filled with nothing. The design has an atomiser hidden in its cap with 2 ml of perfume. The body of the perfume bottle is only from glass with the visualization of the air bubbles in the liquid.
Nice idea and very clever result. The perfume bottle becomes small conceptual artwork.
