Phoenix Star 8.5 Inches glass cup shaped oil rig PHX607 looks like Starbucks cup at the first sight. But the glycerin dab rig is more than that. It's Starbucks cup-like shape allows the oil rig to stand in a stable manner and makes it portable. You can easily take this starbucks dab rig out for traveling, outing or just outside. This starbucks dab rig measures out at 8.5 inches in total height and includes a quartz banger. What makes this glycerin dab rig so fantastic is that it is with colorful pure glycerin inside. You can put it in freezer for 1 or 2 hours and get the coolest hit. Just like drinking a cup of iced coffee on a hot summer day, the feeling is awesome.
