I have on this listing a Used Barbie lunch box and the Barbie thermos.  Both are made from Thermos. And both are dated 1990.  

I found these at a farmers garage sale.  They were in a box and we very dirty.  He said he forgot he had them but needed to not keep them because he was moving into an assisted living apartment.  Everything had to go.  Like I said they were in bad condition..layers of bird you know what, dirt, straw, and wrapped in old news papers dated back in 1995.  They did wash up nicely though even with Dawn dish soap and a little elbow grease.  I will go over them again when they are sold.  There is still residue from masking tape on it yet.  That too will come off with a little work.  But you are buying them as shown in the photos.  

I see some water marks on the front sticker and quite a few marks on them as he said his kids used them a lot taking their lunches to school.  Like I said...check out the photos as they are part of my description.  Some rusting to the clasp...but works great.

I will be listing the other kids lunch boxes found at this farmers sale very soon too....check them out.
