Flimsy
These are flimsy containers that don't seal that tightly.  They're suitable for one-time use.  For example, if after a holiday dinner you send guests home with leftovers.  All the storage containers I have previously acquired have been much sturdier.  In fact, many supposedly one-time use containers I get with various foods are sturdier and more reusable. Go for these only if you hold large dinner parties and don't want to see the leftovers or the containers ever again.
