Retulp is a designer and manufacturer of sustainable drinking bottles with a good story. Most bottles are made of stainless steel because it is the most durable material. We also have a series of bio-based bottles made from cane sugar. For every bottle sold, Retulp donates 1000 times the content of drinking water through the MADE BLUE foundation to developing countries. This way you can contribute to a sustainable future for someone else. With which Retulp bottle do you ensure that someone on the other side of the world drinks with you?
