Handy box for one person or when there is a little or not cooked food, which is a shame, when you get the boxes there is no complete connection to plug in the vacuum machine, j 'I was forced to buy a length of a food pipe diameter 8 meter so I can use it, and connect it directly to the output port of the machine, it is far from partique be? A nothing wrong with this because these boxes also go in the microwave, it's great.
