Idea of Study Filled Icon
There is a book open in the middle of two pages. On the left page there is four descending horizontal lines, and next to each line are some dots. On the right page there is three descending horizontal lines each with dots next to them as well.
This is a Study 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.
