CURMIO Oxygen Tank Backpack, Portable Oxygen Cylinder Carrying Bag for Travel, Gray, 1 Count (Pack of 1), Traveling

Is the back of this padded the way the shoulder straps seem to be, so there is a cushion against the back?

does this come with the oxygen tank?

Why do they put the wrong gromet size in these bags?

how are you all getting the tube through the hole??? The end of the cannula is too big to fit through the hole?? And this is an infant cannula even….
