Stemclas was founded by a group of PhDs in various science fields. From our reserch career, We realized that STEM is not boring. In fact, STEM can be beautiful, colorful, and joyful. The beauty of STEM shouldn't stay only within the laboratory. Instead, this beauty should be displayed to the public, especially to the younger generation. From then, we decided that it is our mission to make this happen. Our strategy is to let children learn STEM when playing. These unique educational toys combine STEM knowledge, creativity, and joy together, promoting our children's development in STEM fields.
