Idea of Bureau Filled Icon
This looks like three rectangles on top of each other. The very top one is smaller and longer. The two bottom ones have a line in the center of them, going horizontal. There are two tiny squares on the bottom of the bottom rectangle, on the edges.
This is a Bureau Filled 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.
