Imagine an indoor ellipse-shaped cycling track with glass balls speeding at high speed instead of bicycles. Now imagine two little children's hands interested in all the fuss on the track. Suddenly one ball disappeared, another was stopped, and another appeared, but in a different size. Lots of fun, laughter, ideas, and possibilities. It was the children's fun that inspired us to create the Koban lamp series. The ellipse-shaped metal frame and glass balls arranged with youthful spontaneity and courage attract the eye, giving the character of the space in which they are located. Koban lamps can be freely mounted: hung on the wall, as a sconce on the ceiling... We are limited only by imagination. When arranging a living space, it is also worth listening to the voice of your inner child.
