Unique portable French Press. No need to transfer your coffee or loose tea from your old cafeteria, into your travel mug or thermos flask. Do it all in one fell swoop with the ingenious built in coffee press! Just add your favourite fresh ground coffee or loose tea into the flask, add your boiling water, brew, and press the integrated plunger into the flask, finely filtering through those ground beans or loose tea to leave you with a smooth delicious blend of fresh coffee/losse tea, whilst also locking down and sealing the coffee grounds at the bottom of the flask for easy disposal later. Also through a cleaver little stop valve at the bottom of the plunger any coffee grounds are trapped, stopping them from stewing seeping into your fabulous brew.
