This glass dab straw takes a simple design, and adds a touch of cooling power. The small glycerin chamber has a coil tube that passes through the center. Stick the pipe into the fridge for a couple hours to cool down the glycerin, and to avoid the tip cracking during torching due to temperature difference, pre-warm the glass tip with your hand before it makes contact with the flame. Torch the tip until hot, aim into your concentrate, and inhale. Quick and cooled dabs in a stylish, compact package!
