14mm Option *Picture shows 10mm for reference

The XL Diamond Knot is the convenient beat-up banger you have been looking for! The quartz banger is designed to be used without a carb cap/marble, making it a truly innovative design. Additionally, the banger was traditionally intended to be torched clean so though you can soak in isopropyl alcohol to preserve the quality/clarity, feel free to heat clean. The XL Diamond Knot has 6 stacks, all aiming to maximize the banger’s surface area. Great for those who want a simple banger that doesn’t require capping or cleaning.

Overall Length: 4” (102mm)
