The consumption of yerba mate in Paraguay occurs through tereré, a traditional drink in which yerba is poured into a container, cold water is added, and sipped with a straw. It is a drink declared national heritage that does not distinguish social classes and is massively consumed. Paradoxically, the tereré has suffered few interventions over time. This is how TEKÚ arises, a product that seeks to improve the user experience when taking and transporting the tereré. Its integral design unites the thermos, the guampa, and the bombilla with a system of inserts and magnets. It is inspired by the shape of a horn that links it to its origin and whose curved lines adapt to the body. It is complemented by interchangeable covers made with native materials that improve comfort during transportation.
