This is a set of 5 prep/ingredient nesting bowls by Duralex (France) plus 2 of the smaller 2.5" diameter bowls  (I have included a pyrex lid just because it fits and holds them all together (minus the extra 2).  These are perfect for prepping ingredients for cooking and meal-prep.  They are high quality.  One of the small extra 2.5" bowls does not say Duralex but I'm including it anyway.
