Stic lac and Shellac are unrefined forms of shellac, produced from the resin secretions of the Kerria lacca aphid. Stick lacquer is the raw, unprocessed product harvested directly from the trees, while the refined (cleaned and ground) product is known as shellac. These resins are processed into natural lacquers and polishes for wood, instruments, and art objects. Their Vietnamese production guarantees high purity and color consistency, essential for export quality.
