This is an image of the number three sitting in the middle of a circle shape. There is nothing else in the image. It might also look like the three ball from a game of pool or billiards but is more simply a three with a circle around it.
This Circled 3 icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
