The image depicted is a logo of the word 'box' written in lowercase letters. Each letter is an outline and spaced very close together, both of the o's are connected as if to form the letter 8.
This is a 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 13,700 icons, all in the same style and quality.
