Dopper believes crystal clear water is precious in every ocean, from every tap. So we created a crystal clear water bottle as a reflection of our vision. An ocean-saving device with a luxurious appeal. Ready to make a statement. Not just on your desk, but also to the world. The Dopper Glass is the first ever Cradle to Cradle CertifiedTM reusable bottle. Made from borosilicate glass, it’s surprisingly sturdy and created from 100% natural minerals. Turn this bottle upside down to find another hidden superpower: a cup to drink tap water from. Putting water on a pedestal. Quite literally.
