This Usuń link 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 4,300 icons, all in the same style and quality.
This is a picture of what almost looks like an oar (two small ovals connected by a line) with a smaller circle next to it. The small circle has an "x" in the middle of it, and is located on the right side of the link.
