BOOKMAN is a bicycle accessory brand headquartered in Stockholm. The product has a simple design without waste. However, it does not compromise on functionality at all, and I feel the philosophy that leads to Apple products. Its high design has been evaluated, and it is also handled by the Museum of Modern Art (MoMA) in New York. The bicycle lights cultivated in Northern Europe, where the polar night is located, are products with usability above the standard from the viewpoint of safety.
