This is an image of a wine glass. The wine glass has a crack from the top rim going down into the middle. This is exactly like the image you would see on many boxes to indicate "fragile" or "breakable" items within.
This is a Fragile 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.
