The Founders of Senger Naturwelt are highly aware of the dangers of throwaway society and want to convey this to their children. It is important to them that their animals are made of natural materials that are free of harmful substances, are produced in an environmentally friendly manner and are processed in a socially just manner. All Senger animals & teethers are made in Germany from entirely organic and natural materials. They are heirloom pieces that will be in your family for generations.
