I agree with everyone else here. Keep that little rubber thing on them. This can be difficult if you have pets because they seem to steal those caps from me. They don't eat them, just put them in the weirdest places it seems. They do the same to my headphones rubber ends.
I usually keep the cap on plus throw them in a labeled ziplock. I use different ones for different types of flavor and it makes them less likely to be lost or thrown away if they're in a baggie.
