The mechanical grinder easily grinds freshly ground sesame and flax seeds. They are used in sweet and savory pastries, salads, and to decorate sandwiches and cookies. They add an interesting flavor to rice and noodle dishes, meatballs, mayonnaise, instant noodles, chicken or grilled meat. Using ground seeds allows the body to absorb more and better omega-3 fatty acids, vitamins and antioxidants. The grinding coarseness can be adjusted using a thread. Material: glass, ABS plastic, ceramic grinding mechanism. Do not fully tighten the thread to adjust the grinding coarseness, as there is a risk of the ring covering the ceramic thread peeling off. Dimensions: dia. 5 cm, h. 12.5 cm. The glass part can be washed in the dishwasher.
