This is a Course 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 12,800 icons, all in the same style and quality.
The icon has three connected vertical rectangles. The rectangle at the center is slightly than the other two. The first rectangle has a horizontal line towards the top and two towards the bottom, the center one has at towards the top and one at the bottom, and the last has one up top and two at the bottom.
