This is a standard glass dab nail that attaches to most dab rigs. There are different size options available so you can find the right fit for your rig. You can get it in either 14mm or 18mm and you also have the option to mix and match so you can decide if you want the nail, the dome, or both. This dab nail is easy to use and is a perfect alternative to quartz bangers. For this dab nail with glass dome, the dome has color accents to give it a cool little flare. Please know that color options and patterns are chosen at random.
