What is an e-Nail?

[GraceVape]

e-Nails, also known as eRigs, are the electronic version of a dab rig. Used to vape THC extracts, eNails have more advanced, powerful capabilities than vape pens do.

eRigs plug in to an electric source and heat the nail using electricity—no torch is required.
Also, most eRigs come with glass water filtration components so that vapor is filtered for optimal flavor and cloud production.
