Raise your Glass

We know that you know about the plastic soup. Swimming around in oceans far away. Out of sight, out of mind, right? Wrong. Because what if we told you the waters in our so-called backyards aren't exactly innocent either.

Surprise! Plastic is hiding in plain sight. It's not called microplastic for nothing. Tiny pieces of plastic, too small for the eye to see, floating around in the lakes we swim in, the canals we sail in and the rivers we walk by. Not cool. And single-use plastic water bottles? Not helping.

Something clearly needs to be done. Together, you and I can break this vicious circle. Sip by sip.

Newest bottle on a mission

Meet our reusable sea-through bottle

With this bottle, you are raising awareness about the invisible plastics that surround us. Did we hear someone say 'superhero'? Because that's what you are.

So, raise your Glass (Dopper) for crystal clear waters. We're right there with you.

Until all water is clear as Glass.

Let's make it clear

Why Glass?

We believe crystal clear water is precious in every ocean, from every tap. That's why we've created a crystal clear 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.

This sea-through bottle is made from borosilicate glass. Sounds dangerous but isn't. Now, we won't bore you with the technical details - that's what Wikipedia is for. The only thing you need to know is that borosilicate glass is surprisingly sturdy. And it's made from 100% natural minerals. If that's not a win, we don't know what is!

Our Dopper Glass Insulated (450 ml) will just keep your cold water cold and your hot water hot, for just a bit longer. Whether you like your tap water plain, or infused with crushed beans or leaves and herbs, we've got you covered.

we did some research

Just because water looks crystal clear, doesn’t mean it is

We wanted to get to the bottom of things. That's why we did some research. We also collaborated with By The Ocean We Unite, a Dutch foundation that contributes to preventing more plastics from ending up in our oceans. Right up our alley!

Together with this team of ocean-saving superheroes we took samples from water sources closest to home. And guess what! Macro and microplastics are everywhere. Hiding in plain sight. A discovery that needs to be shared.

So, we took our findings and brought them to the public. At Dopper's Seacret - our annual launch party - we displayed our samples.
