The icon is shaped like a square but the bottom center of it does not connect. At the bottom center is a star shape with curved corners and hanging from it is a ribbon-shape. Above the star shape are 3 horizontal lines one on top of each other.
This is a Diploma 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 13,700 icons, all in the same style and quality.
