Aurora is the only fountain pen brand in Italy that produces its own nibs and parts and assembles them in its own pen factory, and has become one of the top 10 family businesses in Italy by producing writing instruments alone. Similar to the situation of Montblanc and Palac, Aurora also derived the fountain pen and ink production line from the long history of fountain pen production. The difference is that Aurora's ink product line is more streamlined, and the recommended dye ink 125 series contains only 3 colors, which is the entire content of Aurora's fountain pen ink, which is produced by an independent company, and Aurora only performs inspections.
 
The 125 series consists of black, blue, and blue-black inks, and 125-B is affectionately known as "Aurora Black" as a dye ink, but it is often compared to Writing Joy Black, which is actually very unfair. In dye black, the saturation of 125-B can be ranked in the forefront, which is why it is often compared with carbon ink, but its fluidity is stronger than that of carbon ink, which is a great ink for treating the flying white of fountain pens. Its non-smudge-free performance is also relatively rare in dye ink, in general, if you don't consider waterproof, 125-B is also a black ink worth choosing, however, 45ml is sold at a price of 105 yuan.
 
125-N blue ink and 125-BN blue-black ink perform similarly to 125-B with high saturation. 125-N blue ink is a more business-like dark blue, which is different from the lively and vivid Baile color Shizuku series Cyanbi and Bailikan 4001 series sapphire blue. The blue-black of 125-BN is comparable to the oxidized iron gall ink, if it is only for the depth of the blue-black ink, without seeking anti-counterfeiting and waterproof performance, Aurora blue-black can also be considered.
