Although the lid closes, but if he is aroma-tight, I doubt times. Furthermore, in the can many grooves and cracks on the floor, where coffee is made pure. When times changed the coffee is not good. Even after a long time not used, it is problematic. Therefore difficult to keep up garnicht clean! Who once had coffee in it that can get hard again clean - and then it's really stupid as sugar (cubes) stylishly storing.
From the outside, there are grooves at the bottom and at the viewing window. Everything is very difficult to keep clean. Hygiene is something else.
For optimal coffee unsuitable (not for pads!), But for storage of other items, as seen through the window what is in the can.
