Each package contains 2 grams of sativa, 'Sour PK,' shatter. --- Shatter is a type of cannabis extract known for its glass-like texture and high potency. It’s named for its brittle consistency — it can "shatter" when broken apart. Shatter is made using solvents (usually butane) to extract cannabinoids and terpenes from the cannabis plant, then carefully purged to create a stable, translucent slab.
