The story of Couple started from thinking about how couples travel and live together and how they can benefit from a modular bottle that appeals to both genders. The aspect of travelling and saving space is another benefit of this bottle. The caps are sealed and open in a two step (with one hand) for opening and closing to make sure the contents in the bottle are not leaking.
The snap fit mechanism connects two bottles together and make sure the bottles are attached and connected at all times. A simple twist at the snap connector separates these bottles into two individual bottles.
