Ribla Group Head for E61 machines, size 8.5

Features: Siniso's calf is characterized by being made of silicone material, which keeps it clean for a longer period and preserves the smell and taste. It does not become very hard over time like other calves, making it easier to remove and reinsert for cleaning. There is no need to tighten the portafilter very tightly before extraction like other calves. It lasts longer.
