The ReLife Ink Cartridge is a printer ink cartridge designed by Kim Jungwoo, Kim Yoonsang, and Park Eunsung that uses every last drop of ink, even when the printer says the cartridge is empty. The cartridge can be turned into one of three different stamps to get the most out of the remaining ink.
The stamps messages are color-coded and are all different. Cyan's message is "Recognition," magenta's is "Confidential" and yellow's message is "Reuse Old Paper." I am loving the idea behind the ReLife Cartridge, but I do think it needs to be a little more corporate with phrases such as "Approved" or "Denied" added to the mix. Being able to customize the stamps would be a great move too. You can check out conceptual images of the ReLife Cartridge.
