Thin Mints are Girl Scout cookies that are round and chocolate-mint flavored wafers that are covered in a layer of chocolate. Thin Mints sell the best out of all the Girl Scout cookies and have never changed their name. Little Brownie Bakers and ABC Bakers both make Thin Mints.
Think Mints are one of the few Girl Scout Cookies that I think have remained the same over the years. I can remember purchasing them when I was younger (and selling them as well). I can't resist picking up a box every year when the girls set up shop outside the grocery store.
