Reflections The art of glass meets the science of pleasure. Doc Johnson presents the world’s first premium vibrating glass. Designed by true artisans in vibrant jewel-like pallets, they’re waterproof, phthalate-free, completely hygienic and easy to clean. And because they’re glass, they transfer an incredible vibration, at any of their three varying speeds. Warm them up or cool them down with hot or cold water to experience an additional boost of euphoria. Sit back, relax and let Peace, Love, Hope, Nirvana, Bliss or Joy take you to Shangri-La. Consider them a reflection of our attention to detail, design and technology. All Reflections are 5 inches long and require 1 AA battery, (not included).
