The icon resembles a a circle loop however the circle does not completely connect. Instead at the bottom center there is a circle that connects the circle to make it complete.
This is a Piercing 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.
