ISO Icon in iPhone Style

This is a ISO 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.
The logo is a rounded rectangle that is longer horizontally than it is vertically. On the inside of the rectangle are the letters "ISO" in all capital letters. The letters are centered on the inside off the rounded rectangle.
