You won't find loose change, a makeup bag or even a key chain in Stana Katic's Campomaggi tote. "I like to keep my purse really simple," the 35-year-old single L.A.-based star of the ABC crime drama Castle (Mondays, 10 P.M.) tells Us Weekly. So what must-haves make the cut?

All Washed Up
"I can't do without face wipes and my Dr. Hauschka Quince day cream. I traveled by horse and camel in Mongolia last year, and it was important to freshen up on the move!"

The Sartorialist
"I speak three other languages -- Serbian, French and Italian -- but typically read in English. I'm in the middle of Slim Keith's memoir, Slim. She was a 1940s style icon who inspired Lauren Bacall."

Mind Condition
"In my line of work, someone may say, 'Guess what? You've got to be on a plane in two hours.' So I keep a toothbrush and toothpaste on me."

Secret Weapons
"I carry Marc Jacobs Magic Marc'er eyeliner and Christian Dior red lipstick to amp up my look in a flash."

Hey There, Sugar!
"Hi-Chew, a Japanese fruit candy, is my go-to treat right now. They're great whenever I just need something sweet."
