I like the Lock and Lock containers. They are glass, with plastic tops. I've seen them at Target, but also at the asian market. They also have a website

Also rubbermaid has recently put out glass containers with the easy-find lid system. I love my plastic ones but will probably switch to the glass ones soon.

I picked this set up at Costco. Glass with plastic lids, and the set has several sizes. I get a lot of use out of them:

i have the anchor hocking refrigerator dishes and i love them but they really are not meant to travel. the tops are glass and just sit top of the containter. i definitely recommend a glass container with a fitted plastic top.

I love, love, love my new Frigoverre containers. The lunch bag set was a little expensive, but it was perfect and I love the way they all stack up nicely in the lunch bag. I use the big one for storing leftovers. The medium one is perfect for sandwiches/mains and I have two of the small ones for side dishes. This was a very happy ending to a long quest for lunch containers.

I got mine at a MarketDistrict (Giant Eagle)

Also, glass containers seem to be easier to wash than plastic, so I just handwash mine every night and find that I don't need to own as many sets.

The trick to pyrex is to put the 1 cup inside the 2 cup inside the 4 cup inside the 7 cup..and then stack. I can get three high in my cabinets, and they are fairly steady. Not little kid safe, but they're not going to fall unaided, either. All the tops go in an open white plastic basket (prettier than it sounds, honest) on top of my fridge.

Technically, you're looking for containers that "nest", not "stack". Finding ones that nest well when they're all the same size is hard, but I do have a few with the "Glasslock" brand. They are the glass ones with the plastic lids that solidly snap on. You have to look for the ones with the steep slope to the sides -I have other Glasslock ones that do not nest.

I like 6-ounce custard cups with snap-on plastic lids. You can cook your breakfast in them, zap, store in the frig, and carry in a bag. Perfect for 1/2 cup of yogurt plus berries or a baked egg&veggies. The 10-ounce size might be nicer for lunch.

Don't forget our wonderful and cheap friend- the canning jar!!! I hate plastic containers too. They are stinky and icky after a while. So I take 16 oz wide mouth canning jars (that sometimes I use for canning or other food storage) and send my husband to work with those! The lids with bands work fine, but so do the plastic lids you can buy separate. They travel great and when you have wide mouth they stack nicely. I see a lot of other posts here that are very expensive and that seems silly to me when I have a giant cabinet full of jars. I send my husband to work with soup in quart jars. If you are worried about it breaking- which is my only concern besides leaking- make a cozy!! A couple towels together, sew and voila, you can even add a handle for a very cheap and environmentally safer option. Go glass!!

Frigoverre are perfect for packing lunches and stacking in draweres!

I've had this same problem. And while I love my Lock and Lock containers and the Snapware ones from Costco, they do NOT nest well. In fact, the ones from Costco get stuck sometimes, and my frustrated husband has chipped the rims on two different occasions trying to get them out.

What about a stainless steel tiffin carrier (available at Indian markets as well as places like World Market) when your lunch doesn't need to be heated and plastic bento boxes if you need to microwave it?

We use Anchor Hocking with plastic lids for leftovers. They do nest nicely.

I love my set from costco (not snapware, another brand) but I don't nest them either, I stack them with the covers on.

Also, if it is the heating/eating in plastic that bothers you, you could keep a nice glass or ceramic bowl at work, carry your lunch in plastic and then pour into your nice dish at the office.

This might seem like a stupid suggestion but you could also consider do you really need so much containers? Instead of a set, maybe only keep on hand a limited amount to minimize the footprint in your cupboard. I've found I can get by on just a few. If you buy a set, just store the extras away in the box and replace when needed.

They don't stack at all, but i'm a huge fan of Ball/Kerr canning jars for lunches. They're the closest to leak proof i've ever used, indestructible, and cheap.

Canning jars! They come in so many sizes. They clean up well. They are perfect in every way. If need be, wrap it in a towel to keep from breaking. I've never had a leak or break though and I've been doing it for years!
