I use these for everything I once used the other sealing bags for. The other bags are PLASTIC (boo, bad for the environment and my grandkids) and I am trying to eliminate single use plastics from my life. Stasher sure makes this goal easier. As a point of interest, these bags may seem expensive, however, you don't need as many as you think because you really don't use many plastic bags at one time, just a lot over a period of time. These are so worth the investment!
