"Wholly Hemp wicks are made for those who prefer not to inhale all of the dangerous chemicals that are emitted from lighters and matches. Along with a more pure smoking experience, our wicks provide a less unadulterated taste of what you are smoking. Every Wholly Hemp Wick is packaged in eco-friendly recycled paper, and we ask all of our customers to please recycle. We only have one earth =]"
