These are very, very cool
Ordered these for a friend of mine whose boyfriend is also a bona fide scientist, so I'll know they're both going to love them. Just a really fun, cool design -- bonus points for the nod towards birthstones, which is always an easy gift. Even if you or the recipient doesn't have a "science connection," I really like the serotonin theme and I'm positive my friend will get a lot of questions and compliments (which she'll love because she's always chatting others up). One of the more exciting and fun gifts I've found for somebody this year -- thank you!
