Thank you for viewing. This is the Comandante C40 MK4 LAB SERIES Tigershark Burr. I purchased it from an overseas retailer previously. It is not sold in Japan. [Product Description] This new product is designed for light roasts, with improved sharpness and cutting ability compared to conventional burrs. It features a newly developed burr called NITRO REX. Inspired by the bite of a tiger shark, it employs a unique double shark-tip blade structure. It accurately captures the high hardness of light roast beans, enabling uniform and efficient grinding.
