The icon is of a Christmas candle sitting in a small candle holder. It is white with black outlines. The candle is melting and has a very large flame, which is white with a black center.
This is a Candle 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.
