Red and white checkered plastic button, approximately 18mm in diameter. There is some chipping on the loop for sewing the button on. I kept this as a spare button for pants I used to own. It was stored in a sewing box. Please refrain from purchasing if you are sensitive to used items stored at home. Feel free to ask any questions. - Design: Red and white checkered pattern - Material: The frame appears to be metal coated with a ceramic-like texture. It might be plastic. - Size: Approximately 18mm in diameter Thank you for looking.
