Single-Serve Disposable Filter Bag (Cup-On) is an ingenious coffee-brewing method that has been around in Japan for quite a while but is lesser known in other parts of the world: Cup-on single-serve drip coffee bags (AKA  Single-Serve Disposable Filter Bag). Several names know them, but the common idea behind them is the same: The perfect amount of ground coffee for making one cup of coffee is contained within a filter bag. This filter bag is equipped with a clever piece of paper engineering to stabilize it safely onto your cup. You must pour hot water onto the ground coffee inside the filter bag and, voilà! You have a fresh cup of dripped coffee within the shortest time and with the minimum possible amount of work and equipment involved.  

What sets the Cup-On single-serve drip coffee bags apart from other pour-over filters in the market is its unique '4-point system.' This innovative design prevents the coffee filter from soaking after pouring, ensuring a consistent and flavorful brew. Even among the variety of cup-on filters in Japan, this particular filter stands out as one of the most premium types, designed for the discerning coffee lover.
