You can not use an eNail without having a trusty nail attachment. Many eNail kits, for example, the Pulsar Elite Series, comes stock with a universal titanium nail. Many people prefer the flavor and heat response of quartz. The 20mm domeless quartz nail is great for low temp vaping to get the most out of your materials. We carry quartz eNail attachments in all 14mm and 18mm male and female sizes.
