This is a Fresnel Lantern 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.
The icon looks like a cardboard box, with the flaps open, if the viewer were standing directly above it. framing the upper side of the box is a semi rectangular line. Inside the box are centered two circles, one inside the other.
