The Clever Coffee Dripper combines the best features of French press and filter drip brewing. By adding a stopper to the filtercone, the Clever Coffee Dripper combines control over steeping time with a sediment-free cup. We call this a "full immersion brewing" method.
The dripper will fit on cups and thermoses with tops wider than 1.5" and less than 3.75" in diameter. BPA-free Plastic. Not dishwasher or microwave safeX
