Query: Robust and useful for larger bags

These are especially good for larger bags requiring sealing and match the set of smaller ones I purchased perfectly well. Living in three places, two where ants are a problem (New Zealand and Hawai'i) and one where weevils are (France), it is good to be able to seal things off for storage in the pantry or in the fridge-freezer.
