The Circuit Rig Double Base from Grav Labs utilizes a unique design to cool vapour while using a minimal amount of water. The included domeless quartz nail sits perfectly on the 14.5mm male joint, ensuring you’re ready to go right out of the box. All in a cozy 6 inches.
Small and Strong
Don’t be fooled by the small capacity – when it comes to vaping concentrates, the Circuit Rig can easily hang with the big boys.
