I just checked my IKEA 365+ containers and they are made in Czech Republic! Despite the sometimes cheap stuff IKEA offers i think these are well made. They seal well, can be put into the oven / freezer (i did both) and are stackable (without their lids). The base is fully glass, the top part is plastic but i think they even offer separate lids if you so desire.
Caran D’Ache for Switzerland (i hope they don’t produce their stuff elsewhere). They are mentioned on the first linked site.
