The object has the number "eight" in the center of the image. The number "eight" has a perfect circle surrounding the eight. It looks similar to the image on an eight-ball in the game of pool.
This is a Circled 8 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 13,300 icons, all in the same style and quality.
