The icon is shaped like a circle but the top right corner of it doesn't fully connect. At the center of the circle is a check mark. The end of the check mark sticks out the opening in the circle a bit.
This Checked icon has Android KitKat style
. If you use the icons for Android apps, we recommend using our latest Material Icons icon pack (please check our sidebar on the right). Otherwise, it's a solid icon pack that looks good in small resolutions, either on the web or in print. It's characterized by thick lines, smooth corners, and is optimized for 24x24 pixels.
