This is a Colon 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 12,600 icons, all in the same style and quality.
The image looks like a long deflated balloon that is in the shape of an upside down letter U. The edges are not smooth. They are bumpy along the inside and outside of the balloon shape. One end of the balloon tapers to a point.
