Demon Killer Muscle Cotton uses a proprietary purifying process at their state-of-the-art GMP-certified facility that removes all impurities, natural oils, and pesticides to ensure that the wick is 100% tasteless. This gives the cloud chaser the purest taste without any unwanted flavor and no break-in period needed. The Muscle Organic Cotton also absorbs and holds e-juice better than other-ecigerette wicks, keeping your coils juiced so you can go for longer durations.
