They look to be in excellent condition!

Vintage Mid Century David Douglas Serving Bowl & 10 Salad/ Cereal/ Soup/ Bowls Retro

The big bowl is about 10" across & about 4" tall,  the smaller bowls are about 6 1/4" across & about 1 3/4" tall.

Please look at pictures as part of the description, these look barely used to me, they are made of a high quality plastic or rubber type material I believe, I know they are not glass or metal, but not quiet sure the proper material, I know if you dropped on it shouldn't break, because they are durable.

Thank you.
