EVOLAB’s Alchemy cannabis oil is a combination of their potent Chroma oil, with a strain specific terpene concentrate focusing on heavy flavor profiles. The all metal cartridge is the perfect delivery mechanism, sporting larger than average air inlets and oil holes, all in a leak-proof design. The durable tank is also designed to be refillable so once the oil runs out, stop back in for a 1000mg refill. Best kept upright, disconnected from the 510 thread battery when not in use and kept out of extreme heat and cold. Max voltage 4v.
