If you want to carry multiple spices in small amounts, go to your local hood corner store and get the drug dealer bags. You can get the tiny nickel bags for single use stuff or even go with the larger gram bags depending on your needs. They are cheap as hell and when they are empty you can just toss them in the river when you're taking a piss.
Along those lines, they sell tiny glass vials that some people put ten bags in too. Never seen those at the corner store but I'm sure you can find them online. They are just big enough for like 100mg of whatever. Maybe search for "cologne sample jars" or something.
