This Karta gwarancyjna 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.
The icon is shaped like a rectangle shape. Inside of the rectangle is a shape that slightly resembles a 10 point star. Attached to the bottom of the star shape are two ribbon shapes sticking out from both the right and left side.
