The Rock Slide makes slide tubes that are better shaped than traditional and provide increased flexibility and comfort. This one is in size medium and shaped after the finger and the hand, i.a. rounded/sloping for better mobility and is wider in the opening but tighter inside.
The Molded Glass Rock Slide is nothing short of cutting edge in the slide world. Many said it couldn't be done, but these slides feature everything you love about your Rock Slide like the tapered interior, finger rest & knuckle cutaway all in a flawless glass finish. They ALL feature a 4mm thick wall.
