I bought these because we have the same style at work and I love the ones we have. Im not sure if the same company makes them but ours are branded a little different. I work for Fire Department that provides both Fire and EMS services. We were coming back from a long transfer once and a patient with a lung infection had been spitting into the bag the whole way. It was right full once we arrived at the hospital. On the way out they dropped it right at my feet from 4ft off the ground. I cringed and closed my eyes, expecting to get covered in the nasty spit and infection combo but... Nothing. The bag did its job and nothing came out even with a big drop. If these are anything like the ones we have at work, these will work fine for the average passenger tossing their cookies. Do note, you have to hold it how it is shown in the picture to make the top open up, otherwise the tossed cookies will end up everywhere anyways.

Fantastic
