This Bat 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 5,500 icons, all in the same style and quality.
Idea of Bat Icon by Siska
We've received the idea on September 14, 2013 and created the icons on November 12, 2013
With Halloween coming near again icons like these would be nice: pumpkin, spider, spiderweb, ghost, black cat, coffin, mummy, headstone, bat, candy.
