I received these as a gift and so far they work really well. It's really nice to be able to grab one of these and wrap up half an onion vs having to dig through our mess of containers and lids. I also like that they're much more durable than foil.
I feel like I'm a little late to the party with these beeswax food wraps. Since I'm cooking more than ever (and trying not to waste food), I was constantly running out of food storage containers and resorting to plastic bags or wrap. These are great because they are eco-friendly and don't take up a lot of storage space. They require a few seconds of warming in your hands before they'll attach properly, which I use as a reminder to take a few deep breaths!
