This JUMBO XXL Dish 4mm Quartz Banger Domeless Nail features an extra large jumbo heating surface.
The nail is 4mm thick so this nail is great for taking large juicy dabs. The thicker wall means it will retain heat longer so you can take both super large dabs and extra low temp dabs.
The XXL dish means it won't work with your standard carb caps so make sure you have a compatible cap. The diameter of the dish is approx 25mm
You can see the AA battery for size reference.
