The image is of the head of a person. The person has a cloth on their face that covers most of the face. The eyes and eyebrows of the person are visible. The cloth of the faces ties in the lower left part of the image.
This is a Ninja Head 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.
