We Currently have 6 diff strains in, in our Lab Pur Carts! We have carried most vape companies over years Cannabis Club, London Donovan, PurDistilled  and many more and the LABPUR has won us over, they **** these other companies out of the water, the quality of the product is bar none, and they are flavoured! Each strain is made from the true strain EX. If you order a Train Wreck cartridge. The distillate would of been derived from the Train Wreck  strain of flower! 
  The taste and the high are absolutely unreal! It's the perfect choice for the busy on the go smoker! And it's nice an discreet being a vape pen, and having next to no smell when smoked! 
 Try one out we guarantee you won't be Disappointed!?
