Guys you’ve lusted after our Molecule Jewelry for a long time and were briefly placated by our Testosterone Keychain. Now here’s your chance to proudly sport serotonin on your person: the Serotonin Tie Tack.

Serotonin is responsible for the regulation of mood, sleep, and appetite, among other things, and low levels of it can be responsible for anger and aggression. So if you’re suffering through a boring presentation by a bunch incompetent underlings right before lunch, glance down at your stylish tie tack and remember to keep your cool.
