The Red Eye Glass 5-inch Sigma is a compact concentrate rig built for discreet, on-the-go dabbing. Despite the small size it filters well, with a two-hole percolator that breaks the vapour up through the water for clean, flavourful hits, and the two-toned orb body gives it a distinctive look. It comes as a set with a matching carb cap for airflow control, so it's ready to use. It's built in borosilicate glass to take the heat, and comes in a few colours. At 5 inches it's about as portable as a rig gets. A good pick for someone who wants a complete, compact setup they can travel with.
