I know these are from 1988 or older because they are marked Stainless Steel Paul Revere 1801 & they went bankrupt in 1988 & no loner used that marking.
They will last forever probably because they are stainless & people rave about how great they are with the rings.
These have FLAT BOTTOMS.
When people blog about which bowls to keep or get rid of when they have too many, everyone says to keep these. Although I am not
The large bowl is approximately 8" diameter x 4.5" deep
The middle bowl is approximately 7" diameter x 4" deep
The small bowl is approximately 5.5" diameter x 3" deep.
No lids - sorry.
