This is a Empty Box 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 12,600 icons, all in the same style and quality.
It is a 3-dimensional box. The box itself appears to be open and empty, as there are 2 flaps open (one each on the left and right), and you cannot see anything inside the box. There is a horizontal line on the front face of the box, near the top, which indicates a handle.
