DURABLE AND TIGHT - The reusable K-cup from K&J has a sturdier, more rigid construction and tighter lid seal so that you will never have another coffee-ground-blowout mess ever again! The micro-etched stainless steel mesh is the perfect size to brew even fine grinds of coffee without leaking or getting clogged. ECO-FRIENDLY AND WALLET-FRIENDLY - Allows for up to 80% savings by reusing one pod instead of buying disposable K Cup coffee pods. Huge reduction in landfill waste too! MORE DRINK VARIETY - Brew the things that you'll never find in a pre-made K-cup, like your favorite fresh-roasted Kona coffee or a toasty, clean genmaicha green tea.
