Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
This is a drawing of a sort of star shaped object but it is not a perfect star the lines are not straight they are curved. In the middle of the start there is a big dollar sign taking up most of the middle.
