This Push Pin 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 15,600 icons, all in the same style and quality.
This logo is representative of a push pin. It has a thin line protruding from a shape that is similar to an hourglass. The line represents the sharp part of the pin and the hourglass represents the part you grab with your hand to push it into whatever you'd like to adhere.
