Eurosealer Informative - Really works
I honestly didn't think it would work very well, but it does. I've had some marshmallows in the pantry for about 5 months now, and they are still soft. It's like they were never opened.
It is a little hard to use. You have to work to get the hang of it. They actually repeat that over and over in the instructions. It's not great for impatient people but if you can learn how to use it (it's really not hard) it works great!
