The unique design by Rinke van Remrtel, the high quality materials used for production (BPA and phthalates free) and the practical cup hidden in the cork make this what you need! The bottle comes in just three parts - so you can wash it by hand very quickly or just toss it in the dishwasher. It is also worth adding that Dopper bottles have become a very important part of Dutch culture. They owe not only their unique design and build quality, but, above all, their social mission. By using reusable bottles, we can reduce the amount of plastic waste. In addition, 5% of the company's profits go directly to the fund, which supports, among other things, projects related to the supply of drinking water in Nepal and ocean cleanup.
