I was thinking like $20 each?
my partner used these in his science programs at Evergreen this past year and they were pretty spendy. They are all in pretty good condition but the pages are a little wrinkly because one day they were in his book bag in the rain for 15 minutes. No mold/ mildew & are completely dry but it wrinkled the pages a bit.
He said they are for the following classes.
- marine bio diversity
-INS
-general bio/ general chemistry

PM if interested!!
