Idea of Great Britain Filled Icon
It's a logo of the flag of the United Kingdom. It's a rectangle with a cross in the middle then another thinner cross outlining that with lines going diagonally out of it to the edges too.
This is a Great Britain 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.
