From the Vendor: Our new Red Borneo strain will allow you to experience the natural taste and potency all Kratom enthusiasts love. This strain is 100% pure red vein leaf cultivated in the region of Selimbau and harvested at peak maturity to ensure the maximum potency for our customers. This leaf is extra powerful because of the fermentation process we have perfected which has enhanced the strain. We have incorporated a four day drying process after harvest to assist in the efficacy of this leaf to help boost the potential of the powder. If you love a good red strain, this pure leaf is a product you definitely want to try today.
