Karing Kind Labs has been researching and developing Co2 extracts since Colorado legalized commercial cannabis in 2010. We have developed a new line of vape cartridges that are specifically designed for our Karing Kind Labs pure uncut oil and our cannabis distilled terpene rich oils. Our carts are unique because we use a wickless system with a ceramic coil. OUR CARTRIDGES ARE DEPENDABLE and over the last 2 years we have rigorously field tested them. Not only did they perform exceptionally well, but the carts have a documented failure rate of 2% – even after being abused and exposed to extreme conditions and harsh climates (hot car in summer, ski slopes in winter, etc).
