The icon looks like it is a plain page of paper with a dog eared corner. Placed on the paper are the capital letters "FLV." One would normally think this icon associates with some sort of computer file.
This is a FLV 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.
