Atmospheric Color Scheme (waterproof)

The sky might be the place where we can be the nearest to blue. To prolong the quality of our inks, we made our inks water-proof in this collection. I think this is our way to keep the hues that have witnessed the development of the Earth throughout the history in our lives. So, even when the dark creeps in, the color of the sky will never fade in our minds. capacity ：30ml
