Idea of Paper Clamp Icon
It is a combination of 3 shapes. On the bottom is a short but wide rectangle. Directly on top of that is an upside-down isosceles trapezoid. Layered on top of the trapezoid, but also directly on top of the base rectangle, is a triangle that instead of coming to a point at top has an oval-like bulb.
This is a Paper Clamp 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 13,900 icons, all in the same style and quality.
