Cavi Cone is the World’s Strongest Pre-roll . For those who need a consistent and reliable product, the Cavi Cone is exactly what you need. The Cavi Cone is a pre-rolled cone that comes packaged in individual travel and storage tubes. Inside the perfectly-packed cone, you’ll find our signature Caviar Gold (a combination of the perfect bud, hash oil, and kief) as well as even more hash oil – making it *the* strongest pre-roll available. Aroma: Cavi Cones carry a surprisingly strong scent for a pre-roll.
