Finish is on a mission to stop people from rinsing their dishes before loading the dishwasher—because that small habit wastes a lot of water. To help get the message across, we designed a limited edition bottle cap that does more than just seal the product. Once detached, the cap turns into a water-saving tap aerator that helps reduce water flow straight from the sink. We engineered the design to feel like a natural extension of the bottle—visually seamless, functional, and surprisingly elegant. Produced using high-quality 3D printing, the cap became more than a message—it became a solution. The project was widely recognized and picked up multiple design awards, including a Silver Cannes Lions.
