Fair, sustainable, and cost-efficient production

We manufacture most of our products in Changzhou, China, where we have modern, largely automated production facilities and benefit from the proximity of important suppliers. We pay attention to ensuring fair production conditions, comprehensive occupational health and safety, and adequate pay for our workers there. In this way, our employees are more satisfied, increasing manufacturing quality and minimizing waste. This enables us to produce more sustainably and environmentally friendly than the competition, but at the same cost. Come, see for yourself and visit our production facility
