I really like these containers because of how well they are made. The different colored lids and being able to write on them is nice. The size and thickness of the plastic makes better than your average ziploc container. The lids come off super easy without much turning. I use these for different cat treats. Most cat treats come in pouches with a ziploc top. These are so much easier to treat your cat from. Opening and closing all those bags was time consuming. They keep the treats fresh, a couple have a softer consistency and still do a month later. Cats are picky and he still eats all the treats I have stored in them. So I think they do a good job. For me they make my life a little easier.
