These are great!  I personally love all the sizes.  I'm an organization queen, so I NEED containers with lids.  Glass containers at this price point were SUCH a bargain!  The lids snap on quite nicely.  I dropped on almost immediately (I'm a klutz) and it didn't break.  So they are also well made, heavy, and not fragile.  I've been loving the organizational ideas from Wayfair!
