The Pulsar Knuckle Bubbler Cone Holder is an innovative, wearable glass piece specifically designed to introduce water filtration to dry herb pre-rolls and cones. Shaped to resemble traditional knuckles, this unique bubbler slides comfortably over the fingers for an ergonomic and secure grip, making it easy to handle during solo sessions or when sharing with friends. Crafted from durable borosilicate glass, it effectively cools and diffuses draws, delivering noticeably smoother hits while keeping lingering odors off your hands. Measuring 5.5 inches in height, this accessory prevents the tips of rolled goods from becoming damp, appealing to dry herb enthusiasts seeking a highly functional filtration device.
Wearable Ergonomic Grip
Designed to be worn comfortably across the fingers, this bubbler provides a highly secure hold that minimizes the risk of drops. The recognizable knuckle shape offers an intuitive grip for effortless passing and handling, ensuring stability throughout your session. Measuring 3.35 inches in width, the design perfectly balances novelty aesthetics with practical, daily usability.
Built-In Water Filtration
This bubbler transforms standard dry herb pre-rolls into a refined, water-filtered experience. By pulling the vapor through the internal chamber, the device effectively cools and diffuses the draw, significantly reducing harshness. The piece features a spill-resistant interior design, carefully engineered to keep water safely contained inside the chamber, even when tilted or passed around during group sessions.
Universal Tapered Cone Joint
The device features a versatile 45-degree angled joint designed to accommodate a wide variety of standard-sized cones and pre-rolls. This specific angle provides optimal visibility and distance from the face while in use. Furthermore, using this holder ensures improved hygiene by preventing the mouthpiece of your roll from getting moist, clogged, or physically pinched shut by scented fingers.
Secondary Standalone Functionality
Beyond serving as a holder for rolled material, this piece doubles as a functional standalone device. Equipped with an ergonomically placed carb hole located just below the mouthpiece, users can easily control airflow and clear the chamber. If you run out of rolling papers, the high-quality borosilicate glass construction accommodates standard dry herb as a traditional glass piece.
