Very very durable.
I use these for pantry, fridge and freezer and they last for years. Many are over 15 years old and still going strong with repeated use. They are the only seal I use on store bought frozen vegetables in the freezer.Report abuse
These are the best things I've found ever .so easy to use . They have made a great difference to putting stuff in my freezer and in my veg bin . So thank you so much.Report abuse
