Kief is made up of the resin glands or trichomes of the cannabis plant. It is separated from the rest of the plant matter, and is basically pure THC concentrate. Hash is the result of the separation of the THC or trichome resin glands of the cannabis plant separating from the plant material itself. The pure THC or kief is then generally pressed into a brick shape with heat to form hash or ?hashish? as others may know it as. Our AAA+ grade Mercedes Hash is of the highest quality, guaranteed.
