You cannot beat any amount of kratom that you are only paying 4 dollars for! I'm pretty sure that's even just to cover shipping anyways I picked up a bunch of them to give this vendor a chance. Today I tried their green Vietnam, which is also the first time having this type of kratom. I'd probably try out some more Vietnam strains if they are all this good and that's the best part of the sample pack is you get 2 strains per sample pack! So not only do you get to try one of their products but 2! If you are planning on trying these guys out try the super green indo it's super energetic and streamline!
