GoKi. "Those who take from nature must also give something back," which is why Gollnest & Kiesel, or GoKi, donates a new forest every year to the forest-poorest state of Schleswig-Holstein - one tree for every newborn child. More than 400,000 beech, oak, and maple trees have been planted since 2004. Only wood from sustainable European forestry is used, and they are working to make as many products as possible circular, or cradle-to-cradle. Gollnest & Kiesel is also socially engaged worldwide, creating schools in developing countries where children have the opportunity for education. It goes without saying that no GoKi toy is made by children: "We make toys for children, not by children." In GoKi's own factory in China, Western standards for occupational safety and security are upheld. Toys should be fun and safe. To ensure the highest safety standards, the team in GoKi's quality management constantly tests all products in their in-house laboratory. External testing institutes also regularly conduct extensive tests on GoKi products.
