The Qnubu Cold Brick 4T is designed for three clearly defined user profiles: advanced hobbyists looking for a compact and easy-to-use press, semi-professional producers who need consistent results and precise pressure control, and small laboratories where repeatability, quality control, and standardization are essential.

For hobbyists, it offers a practical and portable solution; for semi-professional producers, it ensures precision and continuity; in laboratory environments, the integrated pressure gauge allows reliable control of weight and density, making it easy to replicate the same process across multiple batches.

The Cold Brick 4T is a hydraulic press built for cold pressing hash, pollen, and botanical extracts, producing compact and uniform bricks while preserving aroma and terpene profiles.
