This image is something seen on computer icons dealing with documents. This icon looks like a portrait orientated pace of paper with its upper-right corner folded down a few inches. On the middle of this paper icon is the text '3FR'
This is a 3FR 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.
