This is a set of 3 kite string ring winders, perfect for a wide range of uses including crafts, DIY projects, outdoor activities, and of course, for kites. I purchased these about 7 years ago for crafts, but they have been stored unused. ・Size: Approximately 12.8cm in diameter ・String Length: Not specified, but judging by appearance, it's likely around 100m (please note this is not certain) Ring winders are attractive because the string is less likely to tangle and is easy to handle. They are convenient items to have for crafts, handicrafts, gardening, and other small tasks. Please take advantage of this opportunity!
