Get ready to store coffee! The Timemore vacuum canister, has some pretty rad features so buckle up and we hope you love it. It is perfect for sealing and keeping beans fresh. If you look at the black Timemore lid, there are some pretty awesome buttons as there tends to be with coffee gear and the bigger one is to basically extract all of the C02 which we think is pretty cool. The other one (incidentally, the smaller one) does the opposite. It opens up the canister, lets the pressure escape, and boom! You have your Columbian roast or South American pods. This product is also compatible with food.
