Pick your Poison. Poison is a line of colognes for the manly man. Targeted at men from 18-30 years of age with a sense of humor, Poison stands out from the pack of men's cologne brands that take themselves too seriously. The set includes a bottle of musk and cedarwood infused Arsenic; Hemlock, with it's hints of pine and clove; and Cyanide, a dusky mix of cypress and myrrh; each with a distinctly adventurous aroma.
