New in package. Ring size 8. From the manufacturer: This glass slide provides a warm, thick tone that accentuates the middle harmonics of your sound, featuring regular wall thickness and a medium diameter. Tempered glass slides are preferred for full, rich tones. They sound warmer and more resonant than metal slides, producing smooth transitions with minimal string noise. Tempered glass slides are the top choice for many acoustic players and they're also favored by electric players who want the purest slide tones possible. Made in the USA.
