I bought this a few years ago and have used it a few times! It's perfect for the coming season! ◾️Size Diameter: Approximately 29 cm (measured when flat) I will pack it as compactly as possible for shipping. In some cases, it may be packed in a compression bag. It will be sent anonymously, but there is a possibility of changing between Rakuraku and Yuyu shipping methods. Thank you for your understanding.
