SUN G.K. logo

Our logo is the sunrise on the winter solstice. The winter solstice is the day the daylight begins to grow longer. We hope our small company will grow its light from here, step by step.

The three rings of light — orange, yellow and white — stand for the three family members who started the company. Look closely at the white light in the center: there are two small cat ears. Our family cat lives at the very heart of the light.
