This is the largest format, 360 ml, of the most famous black from the Intenze range — Zuper Black — sold by us as drawing ink. It is a deep, intense black with fine carbon pigments in a fluid suspension, valued for its smooth transitions from saturated black to diluted grays. The large format is aimed at artists and studios with high black ink consumption, where the price per milliliter matters: compared to 30 ml bottles, you save 40–50%. The formula is vegan, manufactured in the USA under GMP standards, EU REACH compliant, sterilized, and with traceable batch numbers.
Is Zuper Black from the 360 ml bottle the same product as from the 30 ml bottle?▾
Yes, the formula is absolutely identical in all formats. Intenze produces Zuper Black in a large batch which is then bottled into 30, 60, 120, and 360 ml bottles, with the same quality control. There are no differences in concentration, viscosity, or pigmentation. The only practical difference is that the 360 ml bottle requires longer and more vigorous shaking (90–120 seconds), because the large volume of ink needs more time to homogenize.
Who is the 360 ml format suitable for and how do I know if it fits me?▾
The large format is designed for high black ink consumption: an individual artist working intensively consumes a 360 ml bottle in approximately 2–4 months, and a studio with multiple active artists in 4–8 weeks. The simple rule: if you consume over 60 ml of black per month, the 360 ml format is optimal and gives you a 40–50% saving per milliliter compared to 30 ml bottles. If your consumption is occasional, choose a smaller format — after opening, the ink stays optimal for 12–18 months, so there's no point opening a bottle you won't finish.
How do I avoid contaminating such a large bottle and how long does it last after opening?▾
Sealed, the product has a shelf life of 3–5 years; after opening, 12–18 months under proper conditions. The most important rule: do not work directly from the 360 ml bottle. Decant into small working bottles (30–60 ml), labeled with the date and batch number, and then use disposable containers from there. Never insert tools into the bottle and never pour leftover ink back. Keep it tightly sealed at room temperature, away from direct light and extreme temperatures. With these precautions, the risk of degradation over the estimated consumption period is minimal.
Why does it say 'drawing ink'? Can I use it for other purposes?▾
The product is sold with the declared intended use for drawing — this is the only use for which it is sold. Use by the consumer for any purpose other than that stated is strictly the consumer's responsibility, and the store assumes no liability in this case. Our recommendation is to always follow the intended use on the label and the applicable legislation in your field of activity.
How much do I actually save compared to smaller bottles?▾
The price per milliliter for 360 ml is the lowest in the entire Intenze range: you save 40–50% compared to the equivalent in 30 ml bottles, 25–35% compared to 60 ml, and an additional 10–15% compared to 120 ml. Over the course of a year, an active studio can save considerable amounts just by switching to the large format — provided that the consumption volume justifies opening a 360 ml bottle within the 12–18 month window after opening.
How do I practically organize the 360 ml bottle in a studio with multiple artists?▾
The recommended procedure: shake the large bottle vigorously, pour into clean 30–60 ml bottles — one per artist or per work station — labeled with the decanting date and batch number, then immediately close the main bottle and put it back in a closed cabinet at room temperature. Each artist works exclusively from their own portion, using disposable containers. This reduces the frequency of opening the main bottle, prevents contamination, and gives you a clear record of remaining stock at all times.
