Pulsar Ruby Insert For Quartz Banger has a rating of 4.7 stars based on 3 reviews.
This lab-grown faceted ruby insert for quartz bangers provides the best possible flavor from your dabs, more so than quartz, and retains heat better for low-temp dabs. The insert measures 18mm (diameter) x 16mm (height) and works best with standard size 25mm OD banger buckets.
Includes a reusable padded storage container to protect your insert when not in use.
***Note: Do not heat the insert directly or it could cause thermal shock and crack it. Only heat the insert passively through your quartz banger. Banger is sold separately, shown for illustrative purposes only. ***
