Colorful inflatable ring featuring Doraemon characters, perfect for water play, approximately 55cm in diameter. The inner opening is about 20cm. Used for only one season last year. No leaks! I used a tool to inflate it, so I didn't put my mouth on it. The string part was cut off, so there is no string. Still usable. - Design: Colorful design featuring Doraemon characters - Color: Blue - Back color: Blue - Size: Approximately 50cm in diameter Thank you for looking.
