This is a clear acrylic card stand. It's perfect for displaying documents, papers, and more. The horizontal side is approximately 15cm, and the vertical side is approximately 11cm. It's the perfect size to hold a sheet of paper cut into quarters (A4 size). I used these at a wedding favor market to display the descriptions of each gift. They could also be used to display table numbers. They show some signs of use, but are in good condition and do not affect their functionality.
