This is a Cardboard 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 12,300 icons, all in the same style and quality.
A cardboard box is a bunch of rectangles that combine together folding it to mold it as one to make it into a container. On the sides there are small slits that have a handle to grasp it on, these are lines that come to a point in the top-middle of the side rectangles.
