This icon is made up of two rectangles with rounded corners. The rectangles are standing on end so the longer lines are horizontal to the ground. One rectangle is behind the other in such a way that you can barely see it. This represents a billfold that is slightly open.
This is a Wallet 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 13,900 icons, all in the same style and quality.
