"Say goodbye to clumps and hello to the perfect espresso pull with the FusedLine WDT Tool. This highly customizable and stylish design will allow you to get more consistent espresso extractions no matter your technique or portafilter. It includes 9 slots to arrange the included 10 pins with one extra pin. Simply untwist the cap, place the pins, and reassemble. In less than a minute, the tool will be ready to go! The included pins are made of stainless steel and are 0.4mm in diameter. We found this gives the perfect combination of rigidity and flex allowing you to break up clumps for a smooth extraction. After you've finished grooming your grounds, effortlessly drop the WDT Tool into the self-aligning stand to store it away for the next use. The stand is weighted to provide a stable base and quality feel. Any stray grounds will be contained within the integrated catch tray. Simply dump them out or give the stand a quick rinse to keep your espresso station clean and tidy. By purchasing this product, you will receive a WDT tool handle, self-aligning stand, and 10 pins with a storage tube. All components besides the stainless steel pins are 3D printed using high quality, eco-friendly PLA – hand wash only with lukewarm water and soap."
