Dab Nails are commonly used to vaporize essential oils and are an essential for your Rig setup. The Nail is heated up with a torch or in some cases with a coil. The next step is placing the dab on the surface of the nail resulting in vapor for you to inhale.
There are multiple types of dab nails, (Titanium, Ceramic, Quartz, or Glass). Some nails are designed to go inside of the glass joint and usually require a dome to be utilized, while others go on top of the joint and require no dome. Every Rig is unique and each type of nail will function differently depending on your current setup.
