This is a handy little plastic bag sealer. It is compact and takes batteries. I'm not sure how long it is going to last, it doesn't seem like the best quality but so far it has done the job! It smells a little each time you use it because it seems to just melt the plastic together. It takes a few tries to get it right but it works in a pinch. Good for camping but maybe not everyday use.
