Medical Grade - Six Ultra Premium Cones. THC Design's Sativa pre-rolls should be a go-to choice. Each tin contains 3.5 grams of premium, estate grown flower packaged into six artisanal cones for easy and convenient enjoyment. THC Design's XJ-13 is one of the most popular strains on the Estate. Crossbred between Jack Herer and G13 Haze, this Sativa-dominant strain balances high levels of THC with low levels of CBD, making it an optimal option for daytime relief. This strain is fresh with uplifting notes of lemon, tangerine and pine.
