The image is of a singled closed circle with an oval inside. The oval is shaped like the number zero. The edges of the circle and the oval are not touching each other and they are both completely closed. Not other images are touching.
This is a Circled 0 icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
