1. Built-in high-specification classic spring balance system provides a constant vertical pressure of approximately 30 pounds (30 lbs) with each press, effectively dissipating excess force and ensuring consistent coffee grounds compaction for more stable and efficient espresso extraction. 2. Working principle: In the first stage, the top cover/baffle precisely fits the edge of the portafilter, automatically maintaining absolute perpendicularity between the tamper and the portafilter; in the second stage, the tamper disc moves vertically downwards, perfectly solving the problems of misaligned tampering and channeling issues encountered by beginners. 3. The tamper base is made of food-grade stainless steel with a high-precision mirror polishing process, resulting in a smooth, mirror-like surface. 4. Quick tamping, less coffee stagnation, and greatly facilitates subsequent daily cleaning and maintenance. 5. Available in both flat and classic ribbed bottom options to meet different brewing preferences. 6. The handle is crafted from premium natural solid wood, with a finely polished surface that retains the warm, smooth feel of the wood. Its ergonomic design provides a comfortable and easy grip, adding a touch of vintage elegance to your daily coffee brewing experience. 7. Note: Due to the use of natural wood, the finished product may exhibit natural variations in grain, color, knots, and mineral streaks. These are inherent characteristics of natural wood and do not constitute a quality issue. 8.
