Cartridges only requires a battery

He's beat me to it. A standard 510 thread battery is pretty much universal and will work on nearly all carts.

You can use a mod vape but I've found its too powerful even when you adjust the voltage. The optimum level to combust the liquid/oil is 3.7v and the battery shown below is preset at that voltage.

Mj concentrates has had some really good strains, the blue dream and strawberry cough. 1st national is also very good.

Just a word of warning though, just be careful as the carts tend to be very strong and the convenience of tokin anywhere means you can toke wherever, it's very discreet.

Enjoy.

Try some BrassKnuckles? we still got some in stock!

Only tried NDWUK's vape cartridges before, great Zkittles cartridge available from them, not too sure if it's still available, but they sell great cartridges and soon i'm going to venture out buying cartridges from other seller's, but much like bigbudder said thc in the uk is most likely a good option too as i'm going to be purchasing from them at some point in the future and i'm definitely looking forward to it as they have products on here that other vendors don't offer. In terms of a vape you could get i'd just say get a standard 510 thread vape, NDWUK have also just put up their newest product which is a Brass Knuckles pen which i'm guessing is just as good if not better!
