REBOX / Product design concept for used smartphones


The latest smartphone has great features and performance. But, When we meet a new smartphone, the old smartphone is left in the drawer.
Rebox makes it easy to switch to a home device with a smartphone that you no longer use.
The Rebox contains a built-in Bluetooth speaker and adds new functionality to the used smartphone.
When you are home, you can use the display to receive a variety of content, and when you revolve the device, it becomes a security camera. You can view the inside of your home from the outside. You can insert an SD card into a memory slot in the back side to save the recorded image.
