This Maska ucieczkowa icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,000 icons, all in the same style and quality.
This icon represents an escape mask. It is a straight line across leading down to a point with a circle in the middle and rounding back around to the top. In the middle is a small rectangle that has an arched rounded bottom.
