This 5-pack of 12mm quartz drop-in inserts are made for the Pulsar RöK electronic dab rig. When you add a quartz drop-in insert to your RöK, you'll get the best low-temperature dabs with minimal waste. The 12mm outer diameter of the insert provides an exact fit to the dab ring quartz coils of your RöK.  

This pack of five inserts is a certified accessory item for your RöK. The drop-in inserts are made from high quality quartz and are designed for use with concentrates.

These drop-in inserts are an innovative way to low-temp dab without jazzing your quartz banger. It's far cheaper to replace inserts than to replace your expensive quartz banger, making these quartz drop-in inserts economically smart.
