This Żaluzje 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 image is a rectangle that looks like a window. Across the top of the window are horizontal bars like blinds. There is a dotted chain hanging from the right side of the blinds. The end of the chain has a bigger dot than the rest of the chain.
