This Syrena icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
The icon resembles a traffic cone with a rounded top instead of a sharp top. It has a slim rectangular base and looks like an upside-down cup. There are six short lines evenly spread out and emanating from the cone that are intended to give the impression that the siren is making noise or flashing.
