The Pulsar Opaque Deep Banger is made from pure quartz with a flat top, perfect for creating a tight seal with a carb cap to create effective vaporization. The chamber of this banger measure 60mm deep and 25mm wide; the chamber depth ensures a lessened concentrate splash-back and that less vapor escapes through the top and in combination with a carb cap, creates an efficient flow of air. The opaque bottom is alleged to heat more quickly and hold heat longer than a classic clear quartz bottom. These bangers feature a 45 degree stem and are available in 14mm Male and 19mm Male sizes.
