These are selling like crazy online and offline in the US with Asia catching up. Vaporizer FAQ: http://vaporizer-info.com/en/frequently-asked-questions#Is%20it%20legal%20to%20possess%20a%20vaporizer? I have direct access to some named brands and also can provide white label. These will be great for shops as well. I'm based in the US but can ship worldwide. Accepts Paypal, Amazon Payment, or Credit Card via squaredup. MoQ may be required for some products. Edit: TIP- The potential for profit lies in retail or local sales. The margin online (ie. eBay) is still profitable but it won't be much because if you can find this niche, chances are others can find it as well. In addition, >50% of the products sold on eBay are knock offs. I deal directly with the factories and can provide warranties. Focus on local sales like me (ie. smoke shops, craigslist, etc.) and money will come rolling in.
