From the Vendor: Another new addition we are quite proud of. Made from mature leaves you can smell the jungles of Sumatra upon opening. Green vein gets it’s name from the noticeable green “veins” on the backside of the Kratom leaf. The aroma appears to me more stimulating and euphoric then from their red vein cousins. If you are a fan of our Thai Green Vein, this is a must try.
