These are simple to use even your kids could use them. I used these to make frozen yogurt pops. There are many other things you could use these for such as ice pops, homemade go gurt, on the go candy/snack bags, there is endless ideas for these. The tops zip locks like sandwich bags you might buy. You get 50 bags in a set which will last you a little bit. I received this product at a discount in exchange for my honest review.
