The Hourglass Pocket Bubbler Rig from GRAV is a small-scale concentrate rig built for maximum portability. Made from durable borosilicate glass, just like the Lavender Globe Rig Limited Edition and Eclipse Rig Clear, the Hourglass Pocket Bubbler Rig offers maximum sturdiness while its hourglass shape keeps the water level low, allowing vapor to stay dense for extended pulls. Compact and easy to carry, this piece is the ideal travel-friendly dab rig or a versatile bubbler for quick sessions. It comes completely ready to use straight out of the box. This pocket-sized borosilicate glass rig is ideal for concentrate users who want convenience.
