Idea of Stack Filled Icon
This icon is made of 3 rectangles stacked on top of each other like you might stack books on a shelf. Each rectangle has a small black dot in the right corner. The icon is meant to represent things stacked on top of each other.
This is a Stack 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.
