Down Arrow Icon on Transparent Background

This page contains the Down Arrow vector icon, as well as variations of this icon in different visual styles, and related icons. All icons are in the flat vector style, however, differ by the line thickness, fill, and corner radius.
It is an arrow pointed down. The arrow is black on a solid background. There is one solid vertical line. From the bottom of that line there are two smaller black lines extending diagonally up to the right and left at 45 degree angles.

Idea of Down Arrow Icon by Ivan from Icons8

We've received the idea on October 07, 2011 and created the icons on October 18, 2011

Arrows please. In circles and not. First down and right, than the rest.
