PrepSealer - Food Saving Vacuum Container (2L Rectangle + Pump)

will it blow up like the food saver container

Do you sell just the pump? I want to buy the smallest container size but it doesn't include the pump.

Dimension of the 2l square, it says 11.81 x 11.81 x 11.81, l x w x h. please confirm the 3 dimensions?

I purchased this as a gift for my husband and it was missing the valve. So he can’t even use it. How can I get a valve?
