This icon looks just like an old style glass milk bottle. The base is made of a rectangle with rounded corners that tapers to a narrow neck. On top of the neck are two circles meant to represent the mouth of the bottle.
This is a Milk Bottle 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.
