Thats how the the story began, For Cauldryn the bottle itself was an obvious category while the category was massive and with a major push against single use water bottle and coffee cups. The industry as a whole had every cup, mug , bottle and design imaginable different sizes, shapes and colors however they were all fundamentally the same. The burning question was how to enter the market with a truly differential product. The seeds of Cauldryn were planted.

Cauldryn was the first, and to our knowledge the only product that can fully boil ( 212°) water with a battery.
