Having learned about the world of mini-companies through our school, Saint-Boniface Parnasse in Ixelles, our group was gradually formed with a few departures and new arrivals. From the initial meetings and their first crazy ideas a project soon became a reality; the innovative, practical and useful double-compartment isothermal flask. A name? Dubböl. Ecological values, surfing on the awareness of the young and not so young of the perils that threaten our planet. Dubböl has had to and has been able to adapt to the particular conditions of this year 2020, multiplying calls and video-conferences to be able to offer you the best possible project. 8 dynamic, motivated young people with ideas to improve everyday life!
