1. Built-in high-specification classic spring balance system provides vertical pressure with each press, effectively dissipating excess force and ensuring consistent coffee grounds compaction for more stable and efficient espresso extraction. 2. Working principle: Stage 1: The top cover/baffle precisely fits the edge of the portafilter, automatically maintaining the tamper and portafilter at an angle; Stage 2: The tamper disc moves vertically downwards, solving the problems of misaligned tamping and channeling issues for 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 prone to coffee clogging, and greatly simplifies subsequent daily cleaning and maintenance. 5. Available in both flat and classic ribbed bottoms to meet different brewing preferences. 6. The handle is crafted from premium natural solid wood with a finely polished surface, retaining the warm touch of wood. Its ergonomic design provides a comfortable grip and easy application of force, adding a touch of vintage aesthetics to daily coffee brewing. 7. Note: As the handle is made of natural wood, the finished surface may have natural variations in texture, color, knots, mineral streaks, etc. These are inherent properties of natural wood and are not quality issues.
