This is a Z Coordinate 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.
This seems like a Logo but looks more like a keyboard button. It has the a square with the letter Z in the middle. This icon can be similar to the icon or logo of that of a social media icon. But similarly to the keyboard tabs.
