The tamper base knock features a black silicone ring which enables you to gently tap it against the portafilter to shake the coffee grains back into the filter before tamping again. This will ensure that your portafilter will remain undamaged. Add this tamper base to a Concept Art tamper handle of your choice to create your own custom Espresso Tamper!
