NEU Covert is a discreet 510-thread, cartridge battery. This was designed and developed in the United States to help people enjoy their 'concentrate vaping' experiences, given to others, without the fear of being judged or reprimanded.
The NEU Covert was engineered to have a short and stalky battery (with a 510 thread on it) to allow you to attach your cartridge to it and then cover it with a more inconspicuous and socially acceptable outward appearance. The packaging is typical of those used on average disposable, nicotine vapes.
To insert your cartridge into the NEU Covert:
Remove the outside cover (the main body of the 'vape') from its base (the battery w/the 510 threading)
Screw your cartridge onto the battery making sure not to cross-thread the threading
Slip the outside casing back down over the top to snuggly conceal your product from view
Now you're ready to get started enjoying your concentrates, discreetly in public!
