Meaning
The smallest black square in the set, a tiny solid block. It means black and is one of the most popular emoji bullet points for clean lists.
It is everywhere in product descriptions, menus, event details and bios because it is neat and does not distract: “▪️ Size: M ▪️ Colour: beige ▪️ Price: 250k” Without the emoji variation it can show as a plain text character, which still works well. Its light partner is ▫️.
