If you're a camper/hiker/boater, take your lunch to work or are a home keeper that likes to keep things as fresh as you can for as long as you can... You can't go wrong with a product that works pretty much as advertised, and Lock & Lock does just that! My only suggestion is, don't microwave in them. I do seem to have a super powerful microwave, but I find that any fat in the soup does pit them a bit so I avoid it.
If you want a practical idea for a gift (any time of year), don't hesitate to give Lock & Lock!
I gave Ma a set of graduated bowls a couple years ago and she's happy with them too.
Sometimes it's frustrating to match the lids to the bowls...
so that works for me:@)
