Oh, it's so easy to buy things for the females on your list. I have been getting lots of junk mail suggesting gifts for the male grad. As it happens, I know the perfect gift. Try it and you'll see. I learned about it from a hip colleague.
It is: a Lamy safari fountain pen! These only cost about $30.00. I got Frugal Son one in yellow, but there are other cool colors.
Check it out: Lamy safari fountain pen yellow fine
My gift to you.
Any other good gifts for the guys?
