I bought this bag because they have a suitable size for me. First, they are closed with a lock, to know a lot of aircraft fluid bags. Of these, 2 successively installed. With a blue tab should you push this closure. Unfortunately, this did not work well with me and I had to push consuming manually. The effect of Absaugends is astonishing. 2 of 8 bags were filled with air again after about 10 minutes, the rest of the next morning.
