Lethe was created from commitment. This is also the principle that we follow in doing business. We are absolutely faithful to the business culture standards that we have developed.

At every stage of activity, our brand is based on four pillars: people, production, communication and natural environment. We pay equal attention to each of them to be a better company for our customers, employees and ourselves. Simply and straightforwardly.
