Radar Presto 88a durometer, 62mmx38mm - great condition, only used for about a month and a half. Great wheel for a lot of surfaces and great for derby! The wheels are very slightly turning color but are still in almost new condition. If you love turquoise you’ll love these - the color is awesome (that’s why I bought them 😆). These sell for $100 for a set of 8 so this is a really good price. Let me know if you’re interested :)!
