Made in Korea. Colorverse is created by a group of makers with years of knowhow. The inks are treated for hydration and antibacterial properties, so they don't dry or deteriorate easily in pens. It is also designed to maintain the optimal pH balance of 7-8 (neutral). The ink writes smoothly in various kinds of pens and dries quickly on paper.
The ink is made of globally recognised premium quality colourants. It is highly pure with vivid and clear colours. It also has exceptional solubility and great to use in premium fountain pens. Due to the use of plant-based ingrediants, the inks are free from unpleasant chemically odours, such as alcohol.
