黒墨 , What does it mean?

Hello there! A quick post because my friends asked me what 黒墨 meant. It means Kuro Sumi.
Kuro stands for black, and Sumi is ink in Japanese.
Sumi is not the ink used in pens, it's the ink that is used for Japanese calligraphy. Like the picture next to this text. I used this name because it sounded nice actually x') Hopefully y'all understand it now!
