The other day I found the most interesting storage containers at Dollarama - giant zipper seal bags. There are two 20-inch square bags in a package, made of sturdy plastic and they have handles. You can store clothes, toys, Christmas decorations, whathaveyou in them and I thought "what a neat idea!" I'm going to use them to store some Christmas decorations in, to start, instead of the large plastic shopping bags they're in now. Being able to seal the bag will keep moisture and dust out where stuff is stored in the basement.

Are they like the ziploc tote bags?

Yes.
